+Introduction
+============
+
+This file documents the driver for the Rockchip ISP1 that is part of RK3288
+and RK3399 SoCs. The driver is located under drivers/staging/media/rkisp1
+and uses the Media-Controller API.
+
+Topology
+========
+.. _rkisp1_topology_graph:
+
+.. kernel-figure:: rkisp1.dot
+ :alt: Diagram of the default media pipeline topology
+ :align: center
+
+
+The driver has 4 video devices:
+
+- rkisp1_mainpath: capture device for retrieving images, usually in higher
+ resolution.
+- rkisp1_selfpath: capture device for retrieving images.
+- rkisp1_stats: a metadata capture device that sends statistics.
+- rkisp1_params: a metadata output device that receives parameters
+ configurations from userspace.
+
+The driver has 3 subdevices:
+
+- rkisp1_resizer_mainpath: used to resize and downsample frames for the
+ mainpath capture device.
+- rkisp1_resizer_selfpath: used to resize and downsample frames for the
+ selfpath capture device.
+- rkisp1_isp: is connected to the sensor and is responsible for all the isp
+ operations.
+
+
+rkisp1_mainpath, rkisp1_selfpath - Frames Capture Video Nodes
+-------------------------------------------------------------
+Those are the `mainpath` and `selfpath` capture devices to capture frames.
+Those entities are the DMA engines that write the frames to memory.
+The selfpath video device can capture YUV/RGB formats. Its input is YUV encoded
+stream and it is able to convert it to RGB. The selfpath is not able to
+capture bayer formats.
+The mainpath can capture both bayer and YUV formats but it is not able to
+capture RGB formats.
+Both capture videos support
+the ``V4L2_CAP_IO_MC`` :ref:`capability <device-capabilities>`.
+
+
+rkisp1_resizer_mainpath, rkisp1_resizer_selfpath - Resizers Subdevices Nodes
+----------------------------------------------------------------------------
+Those are resizer entities for the mainpath and the selfpath. Those entities
+can scale the frames up and down and also change the YUV sampling (for example
+YUV4:2:2 -> YUV4:2:0). They also have cropping capability on the sink pad.
+The resizers entities can only operate on YUV:4:2:2 format
+(MEDIA_BUS_FMT_YUYV8_2X8).
+The mainpath capture device supports capturing video in bayer formats. In that
+case the resizer of the mainpath is set to 'bypass' mode - it just forward the
+frame without operating on it.
+
+rkisp1_isp - Image Signal Processing Subdevice Node
+---------------------------------------------------
+This is the isp entity. It is connected to the sensor on sink pad 0 and
+receives the frames using the CSI-2 protocol. It is responsible of configuring
+the CSI-2 protocol. It has a cropping capability on sink pad 0 that is
+connected to the sensor and on source pad 2 connected to the resizer entities.
+Cropping on sink pad 0 defines the image region from the sensor.
+Cropping on source pad 2 defines the region for the Image Stabilizer (IS).
+
+.. _rkisp1_stats:
+
+rkisp1_stats - Statistics Video Node
+------------------------------------
+The statistics video node outputs the 3A (auto focus, auto exposure and auto
+white balance) statistics, and also histogram statistics for the frames that
+are being processed by the rkisp1 to userspace applications.
+Using these data, applications can implement algorithms and re-parameterize
+the driver through the rkisp_params node to improve image quality during a
+video stream.
+The buffer format is defined by struct :c:type:`rkisp1_stat_buffer`, and
+userspace should set
+:ref:`V4L2_META_FMT_RK_ISP1_STAT_3A <v4l2-meta-fmt-stat-rkisp1>` as the
+dataformat.
+
+.. _rkisp1_params:
+
+rkisp1_params - Parameters Video Node
+-------------------------------------
+The rkisp1_params video node receives a set of parameters from userspace
+to be applied to the hardware during a video stream, allowing userspace
+to dynamically modify values such as black level, cross talk corrections
+and others.
+
+The buffer format is defined by struct :c:type:`rkisp1_params_cfg`, and
+userspace should set
+:ref:`V4L2_META_FMT_RK_ISP1_PARAMS <v4l2-meta-fmt-params-rkisp1>` as the
+dataformat.
+
+
+Capturing Video Frames Example
+==============================
+
+In the following example, the sensor connected to pad 0 of 'rkisp1_isp' is
+imx219.
+
+The following commands can be used to capture video from the selfpath video
+node with dimension 900x800 planar format YUV 4:2:2. It uses all cropping
+capabilities possible, (see explanation right below)
+
+.. code-block:: bash
+
+ # set the links
+ "media-ctl" "-d" "platform:rkisp1" "-r"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'imx219 4-0010':0 -> 'rkisp1_isp':0 [1]"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'rkisp1_isp':2 -> 'rkisp1_resizer_selfpath':0 [1]"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'rkisp1_isp':2 -> 'rkisp1_resizer_mainpath':0 [0]"
+
+ # set format for imx219 4-0010:0
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"imx219 4-0010":0 [fmt:SRGGB10_1X10/1640x1232]'
+
+ # set format for rkisp1_isp pads:
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_isp":0 [fmt:SRGGB10_1X10/1640x1232 crop: (0,0)/1600x1200]'
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_isp":2 [fmt:YUYV8_2X8/1600x1200 crop: (0,0)/1500x1100]'
+
+ # set format for rkisp1_resizer_selfpath pads:
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_resizer_selfpath":0 [fmt:YUYV8_2X8/1500x1100 crop: (300,400)/1400x1000]'
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_resizer_selfpath":1 [fmt:YUYV8_2X8/900x800]'
+
+ # set format for rkisp1_selfpath:
+ "v4l2-ctl" "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "-v" "width=900,height=800,"
+ "v4l2-ctl" "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "-v" "pixelformat=422P"
+
+ # start streaming:
+ v4l2-ctl "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "--stream-mmap" "--stream-count" "10"
+
+
+In the above example the sensor is configured to bayer format:
+`SRGGB10_1X10/1640x1232`. The rkisp1_isp:0 pad should be configured to the
+same mbus format and dimensions as the sensor, otherwise streaming will fail
+with 'EPIPE' error. So it is also configured to `SRGGB10_1X10/1640x1232`.
+In addition, the rkisp1_isp:0 pad is configured to cropping `(0,0)/1600x1200`.
+
+The cropping dimensions are automatically propagated to be the format of the
+isp source pad `rkisp1_isp:2`. Another cropping operation is configured on
+the isp source pad: `(0,0)/1500x1100`.
+
+The resizer's sink pad `rkisp1_resizer_selfpath` should be configured to format
+`YUYV8_2X8/1500x1100` in order to match the format on the other side of the
+link. In addition a cropping `(300,400)/1400x1000` is configured on it.
+
+The source pad of the resizer, `rkisp1_resizer_selfpath:1` is configured to
+format `YUYV8_2X8/900x800`. That means that the resizer first crop a window
+of `(300,400)/1400x100` from the received frame and then scales this window
+to dimension `900x800`.
+
+Note that the above example does not uses the stats-params control loop.
+Therefore the capture frames will not go through the 3A algorithms and
+probably won't have a good quality, and can even look dark and greenish.
+
+Configuring Quantization
+========================
+
+The driver supports limited and full range quantization on YUV formats,
+where limited is the default.
+To switch between one or the other, userspace should use the Colorspace
+Conversion API (CSC) for subdevices on source pad 2 of the
+isp (`rkisp1_isp:2`). The quantization configured on this pad is the
+quantization of the captured video frames on the mainpath and selfpath
+video nodes.
+Note that the resizer and capture entities will always report
+``V4L2_QUANTIZATION_DEFAULT`` even if the quantization is configured to full
+range on `rkisp1_isp:2`. So in order to get the configured quantization,
+application should get it from pad `rkisp1_isp:2`.

+Writing camera sensor drivers
+=============================
+
+CSI-2
+-----
+
+Please see what is written on :ref:`MIPI_CSI_2`.
+
+Handling clocks
+---------------
+
+Camera sensors have an internal clock tree including a PLL and a number of
+divisors. The clock tree is generally configured by the driver based on a few
+input parameters that are specific to the hardware:: the external clock frequency
+and the link frequency. The two parameters generally are obtained from system
+firmware. No other frequencies should be used in any circumstances.
+
+The reason why the clock frequencies are so important is that the clock signals
+come out of the SoC, and in many cases a specific frequency is designed to be
+used in the system. Using another frequency may cause harmful effects
+elsewhere. Therefore only the pre-determined frequencies are configurable by the
+user.
+
+Frame size
+----------
+
+There are two distinct ways to configure the frame size produced by camera
+sensors.
+
+Freely configurable camera sensor drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Freely configurable camera sensor drivers expose the device's internal
+processing pipeline as one or more sub-devices with different cropping and
+scaling configurations. The output size of the device is the result of a series
+of cropping and scaling operations from the device's pixel array's size.
+
+An example of such a driver is the smiapp driver (see drivers/media/i2c/smiapp).
+
+Register list based drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Register list based drivers generally, instead of able to configure the device
+they control based on user requests, are limited to a number of preset
+configurations that combine a number of different parameters that on hardware
+level are independent. How a driver picks such configuration is based on the
+format set on a source pad at the end of the device's internal pipeline.
+
+Most sensor drivers are implemented this way, see e.g.
+drivers/media/i2c/imx319.c for an example.
+
+Frame interval configuration
+----------------------------
+
+There are two different methods for obtaining possibilities for different frame
+intervals as well as configuring the frame interval. Which one to implement
+depends on the type of the device.
+
+Raw camera sensors
+~~~~~~~~~~~~~~~~~~
+
+Instead of a high level parameter such as frame interval, the frame interval is
+a result of the configuration of a number of camera sensor implementation
+specific parameters. Luckily, these parameters tend to be the same for more or
+less all modern raw camera sensors.
+
+The frame interval is calculated using the following equation::
+
+ frame interval = (analogue crop width + horizontal blanking) *
+ (analogue crop height + vertical blanking) / pixel rate
+
+The formula is bus independent and is applicable for raw timing parameters on
+large variety of devices beyond camera sensors. Devices that have no analogue
+crop, use the full source image size, i.e. pixel array size.
+
+Horizontal and vertical blanking are specified by ``V4L2_CID_HBLANK`` and
+``V4L2_CID_VBLANK``, respectively. The unit of these controls are lines. The
+pixel rate is specified by ``V4L2_CID_PIXEL_RATE`` in the same sub-device. The
+unit of that control is Hz.
+
+Register list based drivers need to implement read-only sub-device nodes for the
+purpose. Devices that are not register list based need these to configure the
+device's internal processing pipeline.
+
+The first entity in the linear pipeline is the pixel array. The pixel array may
+be followed by other entities that are there to allow configuring binning,
+skipping, scaling or digital crop :ref:`v4l2-subdev-selections`.
+
+USB cameras etc. devices
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+USB video class hardware, as well as many cameras offering a similar higher
+level interface natively, generally use the concept of frame interval (or frame
+rate) on device level in firmware or hardware. This means lower level controls
+implemented by raw cameras may not be used on uAPI (or even kAPI) to control the
+frame interval on these devices.
+
+Power management
+----------------
+
+Always use runtime PM to manage the power states of your device. Camera sensor
+drivers are in no way special in this respect: they are responsible for
+controlling the power state of the device they otherwise control as well. In
+general, the device must be powered on at least when its registers are being
+accessed and when it is streaming.
+
+Existing camera sensor drivers may rely on the old
+:c:type:`v4l2_subdev_core_ops`->s_power() callback for bridge or ISP drivers to
+manage their power state. This is however **deprecated**. If you feel you need
+to begin calling an s_power from an ISP or a bridge driver, instead please add
+runtime PM support to the sensor driver you are using. Likewise, new drivers
+should not use s_power.
+
+Please see examples in e.g. ``drivers/media/i2c/ov8856.c`` and
+``drivers/media/i2c/smiapp/smiapp-core.c``. The two drivers work in both ACPI
+and DT based systems.
+
+Control framework
+~~~~~~~~~~~~~~~~~
+
+``v4l2_ctrl_handler_setup()`` function may not be used in the device's runtime
+PM ``runtime_resume`` callback, as it has no way to figure out the power state
+of the device. This is because the power state of the device is only changed
+after the power state transition has taken place. The ``s_ctrl`` callback can be
+used to obtain device's power state after the power state transition:
+
+.. c:function::
+ int pm_runtime_get_if_in_use(struct device *dev);
+
+The function returns a non-zero value if it succeeded getting the power count or
+runtime PM was disabled, in either of which cases the driver may proceed to
+access the device.

+vidtv: Virtual Digital TV driver
+================================
+
+Author: Daniel W. S. Almeida <dwlsalmeida@gmail.com>, June 2020.
+
+Background
+----------
+
+Vidtv is a virtual DVB driver that aims to serve as a reference for driver
+writers by serving as a template. It also validates the existing media DVB
+APIs, thus helping userspace application writers.
+
+Currently, it consists of:
+
+- A fake tuner driver, which will report a bad signal quality if the chosen
+ frequency is too far away from a table of valid frequencies for a
+ particular delivery system.
+
+- A fake demod driver, which will constantly poll the fake signal quality
+ returned by the tuner, simulating a device that can lose/reacquire a lock
+ on the signal depending on the CNR levels.
+
+- A fake bridge driver, which is the module responsible for modprobing the
+ fake tuner and demod modules and implementing the demux logic. This module
+ takes parameters at initialization that will dictate how the simulation
+ behaves.
+
+- Code reponsible for encoding a valid MPEG Transport Stream, which is then
+ passed to the bridge driver. This fake stream contains some hardcoded content.
+ For now, we have a single, audio-only channel containing a single MPEG
+ Elementary Stream, which in turn contains a SMPTE 302m encoded sine-wave.
+ Note that this particular encoder was chosen because it is the easiest
+ way to encode PCM audio data in a MPEG Transport Stream.
+
+Building vidtv
+--------------
+vidtv is a test driver and thus is **not** enabled by default when
+compiling the kernel.
+
+In order to enable compilation of vidtv:
+
+- Enable **DVB_TEST_DRIVERS**, then
+- Enable **DVB_VIDTV**
+
+When compiled as a module, expect the following .ko files:
+
+- dvb_vidtv_tuner.ko
+
+- dvb_vidtv_demod.ko
+
+- dvb_vidtv_bridge.ko
+
+Running vidtv
+-------------
+When compiled as a module, run::
+
+ modprobe vidtv
+
+That's it! The bridge driver will initialize the tuner and demod drivers as
+part of its own initialization.
+
+By default, it will accept the following frequencies:
+
+ - 474 MHz for DVB-T/T2/C;
+ - 11,362 GHz for DVB-S/S2.
+
+For satellite systems, the driver simulates an universal extended
+LNBf, with frequencies at Ku-Band, ranging from 10.7 GHz to 12.75 GHz.
+
+You can optionally define some command-line arguments to vidtv.
+
+Command-line arguments to vidtv
+-------------------------------
+Below is a list of all arguments that can be supplied to vidtv:
+
+drop_tslock_prob_on_low_snr
+ Probability of losing the TS lock if the signal quality is bad.
+ This probability be used by the fake demodulator driver to
+ eventually return a status of 0 when the signal quality is not
+ good.
+
+recover_tslock_prob_on_good_snr:
+ Probability recovering the TS lock when the signal improves. This
+ probability be used by the fake demodulator driver to eventually
+ return a status of 0x1f when/if the signal quality improves.
+
+mock_power_up_delay_msec
+ Simulate a power up delay. Default: 0.
+
+mock_tune_delay_msec
+ Simulate a tune delay. Default 0.
+
+vidtv_valid_dvb_t_freqs
+ Valid DVB-T frequencies to simulate, in Hz.
+
+vidtv_valid_dvb_c_freqs
+ Valid DVB-C frequencies to simulate, in Hz.
+
+vidtv_valid_dvb_s_freqs
+ Valid DVB-S/S2 frequencies to simulate at Ku-Band, in kHz.
+
+max_frequency_shift_hz,
+ Maximum shift in HZ allowed when tuning in a channel.
+
+si_period_msec
+ How often to send SI packets. Default: 40ms.
+
+pcr_period_msec
+ How often to send PCR packets. Default: 40ms.
+
+mux_rate_kbytes_sec
+ Attempt to maintain this bit rate by inserting TS null packets, if
+ necessary. Default: 4096.
+
+pcr_pid,
+ PCR PID for all channels. Default: 0x200.
+
+mux_buf_sz_pkts,
+ Size for the mux buffer in multiples of 188 bytes.
+
+vidtv internal structure
+------------------------
+The kernel modules are split in the following way:
+
+vidtv_tuner.[ch]
+ Implements a fake tuner DVB driver.
+
+vidtv_demod.[ch]
+ Implements a fake demodulator DVB driver.
+
+vidtv_bridge.[ch]
+ Implements a bridge driver.
+
+The MPEG related code is split in the following way:
+
+vidtv_ts.[ch]
+ Code to work with MPEG TS packets, such as TS headers, adaptation
+ fields, PCR packets and NULL packets.
+
+vidtv_psi.[ch]
+ This is the PSI generator. PSI packets contain general information
+ about a MPEG Transport Stream. A PSI generator is needed so
+ userspace apps can retrieve information about the Transport Stream
+ and eventually tune into a (dummy) channel.
+
+ Because the generator is implemented in a separate file, it can be
+ reused elsewhere in the media subsystem.
+
+ Currently vidtv supports working with 3 PSI tables: PAT, PMT and
+ SDT.
+
+ The specification for PAT and PMT can be found in *ISO 13818-1:
+ Systems*, while the specification for the SDT can be found in *ETSI
+ EN 300 468: Specification for Service Information (SI) in DVB
+ systems*.
+
+ It isn't strictly necessary, but using a real TS file helps when
+ debugging PSI tables. Vidtv currently tries to replicate the PSI
+ structure found in this file: `TS1Globo.ts
+ <https://tsduck.io/streams/brazil-isdb-tb/TS1globo.ts>`_.
+
+ A good way to visualize the structure of streams is by using
+ `DVBInspector <https://sourceforge.net/projects/dvbinspector/>`_.
+
+vidtv_pes.[ch]
+ Implements the PES logic to convert encoder data into MPEG TS
+ packets. These can then be fed into a TS multiplexer and eventually
+ into userspace.
+
+vidtv_encoder.h
+ An interface for vidtv encoders. New encoders can be added to this
+ driver by implementing the calls in this file.
+
+vidtv_s302m.[ch]
+ Implements a S302M encoder to make it possible to insert PCM audio
+ data in the generated MPEG Transport Stream. The relevant
+ specification is available online as *SMPTE 302M-2007: Television -
+ Mapping of AES3 Data into MPEG-2 Transport Stream*.
+
+
+ The resulting MPEG Elementary Stream is conveyed in a private
+ stream with a S302M registration descriptor attached.
+
+ This shall enable passing an audio signal into userspace so it can
+ be decoded and played by media software. The corresponding decoder
+ in ffmpeg is located in 'libavcodec/s302m.c' and is experimental.
+
+vidtv_channel.[ch]
+ Implements a 'channel' abstraction.
+
+ When vidtv boots, it will create some hardcoded channels:
+
+ #. Their services will be concatenated to populate the SDT.
+
+ #. Their programs will be concatenated to populate the PAT
+
+ #. For each program in the PAT, a PMT section will be created
+
+ #. The PMT section for a channel will be assigned its streams.
+
+ #. Every stream will have its corresponding encoder polled in a
+ loop to produce TS packets.
+ These packets may be interleaved by the muxer and then delivered
+ to the bridge.
+
+vidtv_mux.[ch]
+ Implements a MPEG TS mux, loosely based on the ffmpeg
+ implementation in "libavcodec/mpegtsenc.c"
+
+ The muxer runs a loop which is responsible for:
+
+ #. Keeping track of the amount of time elapsed since the last
+ iteration.
+
+ #. Polling encoders in order to fetch 'elapsed_time' worth of data.
+
+ #. Inserting PSI and/or PCR packets, if needed.
+
+ #. Padding the resulting stream with NULL packets if
+ necessary in order to maintain the chosen bit rate.
+
+ #. Delivering the resulting TS packets to the bridge
+ driver so it can pass them to the demux.
+
+Testing vidtv with v4l-utils
+----------------------------
+
+Using the tools in v4l-utils is a great way to test and inspect the output of
+vidtv. It is hosted here: `v4l-utils Documentation
+<https://linuxtv.org/wiki/index.php/V4l-utils>`_.
+
+From its webpage::
+
+ The v4l-utils are a series of packages for handling media devices.
+
+ It is hosted at http://git.linuxtv.org/v4l-utils.git, and packaged
+ on most distributions.
+
+ It provides a series of libraries and utilities to be used to
+ control several aspect of the media boards.
+
+
+Start by installing v4l-utils and then modprobing vidtv::
+
+ modprobe dvb_vidtv_bridge
+
+If the driver is OK, it should load and its probing code will run. This will
+pull in the tuner and demod drivers.
+
+Using dvb-fe-tool
+~~~~~~~~~~~~~~~~~
+
+The first step to check whether the demod loaded successfully is to run::
+
+ $ dvb-fe-tool
+
+This should return what is currently set up at the demod struct, i.e.::
+
+ static const struct dvb_frontend_ops vidtv_demod_ops = {
+ .delsys = {
+ SYS_DVBT,
+ SYS_DVBT2,
+ SYS_DVBC_ANNEX_A,
+ SYS_DVBS,
+ SYS_DVBS2,
+ },
+
+ .info = {
+ .name = "Dummy demod for DVB-T/T2/C/S/S2",
+ .frequency_min_hz = 51 * MHz,
+ .frequency_max_hz = 2150 * MHz,
+ .frequency_stepsize_hz = 62500,
+ .frequency_tolerance_hz = 29500 * kHz,
+ .symbol_rate_min = 1000000,
+ .symbol_rate_max = 45000000,
+
+ .caps = FE_CAN_FEC_1_2 |
+ FE_CAN_FEC_2_3 |
+ FE_CAN_FEC_3_4 |
+ FE_CAN_FEC_4_5 |
+ FE_CAN_FEC_5_6 |
+ FE_CAN_FEC_6_7 |
+ FE_CAN_FEC_7_8 |
+ FE_CAN_FEC_8_9 |
+ FE_CAN_QAM_16 |
+ FE_CAN_QAM_64 |
+ FE_CAN_QAM_32 |
+ FE_CAN_QAM_128 |
+ FE_CAN_QAM_256 |
+ FE_CAN_QAM_AUTO |
+ FE_CAN_QPSK |
+ FE_CAN_FEC_AUTO |
+ FE_CAN_INVERSION_AUTO |
+ FE_CAN_TRANSMISSION_MODE_AUTO |
+ FE_CAN_GUARD_INTERVAL_AUTO |
+ FE_CAN_HIERARCHY_AUTO,
+ }
+
+ ....
+
+For more information on dvb-fe-tools check its online documentation here:
+`dvb-fe-tool Documentation
+<https://www.linuxtv.org/wiki/index.php/Dvb-fe-tool>`_.
+
+Using dvb-scan
+~~~~~~~~~~~~~~
+
+In order to tune into a channel and read the PSI tables, we can use dvb-scan.
+
+For this, one should provide a configuration file known as a 'scan file',
+here's an example::
+
+ [Channel]
+ FREQUENCY = 330000000
+ MODULATION = QAM/AUTO
+ SYMBOL_RATE = 6940000
+ INNER_FEC = AUTO
+ DELIVERY_SYSTEM = DVBC/ANNEX_A
+
+.. note::
+ The parameters depend on the video standard you're testing.
+
+.. note::
+ Vidtv is a fake driver and does not validate much of the information
+ in the scan file. Just specifying 'FREQUENCY' and 'DELIVERY_SYSTEM'
+ should be enough for DVB-T/DVB-T2. For DVB-S/DVB-C however, you
+ should also provide 'SYMBOL_RATE'.
+
+You can browse scan tables online here: `dvb-scan-tables
+<https://git.linuxtv.org/dtv-scan-tables.git>`_.
+
+Assuming this channel is named 'channel.conf', you can then run::
+
+ $ dvbv5-scan channel.conf
+
+For more information on dvb-scan, check its documentation online here:
+`dvb-scan Documentation <https://www.linuxtv.org/wiki/index.php/Dvbscan>`_.
+
+Using dvb-zap
+~~~~~~~~~~~~~
+
+dvbv5-zap is a command line tool that can be used to record MPEG-TS to disk. The
+typical use is to tune into a channel and put it into record mode. The example
+below - which is taken from the documentation - illustrates that::
+
+ $ dvbv5-zap -c dvb_channel.conf "trilhas sonoras" -r
+ using demux '/dev/dvb/adapter0/demux0'
+ reading channels from file 'dvb_channel.conf'
+ service has pid type 05: 204
+ tuning to 573000000 Hz
+ audio pid 104
+ dvb_set_pesfilter 104
+ Lock (0x1f) Quality= Good Signal= 100.00% C/N= -13.80dB UCB= 70 postBER= 3.14x10^-3 PER= 0
+ DVR interface '/dev/dvb/adapter0/dvr0' can now be opened
+
+The channel can be watched by playing the contents of the DVR interface, with
+some player that recognizes the MPEG-TS format, such as *mplayer* or *vlc*.
+
+By playing the contents of the stream one can visually inspect the workings of
+vidtv, e.g.::
+
+ $ mplayer /dev/dvb/adapter0/dvr0
+
+For more information on dvb-zap check its online documentation here:
+`dvb-zap Documentation
+<https://www.linuxtv.org/wiki/index.php/Dvbv5-zap>`_.
+See also: `zap <https://www.linuxtv.org/wiki/index.php/Zap>`_.
+
+
+What can still be improved in vidtv
+-----------------------------------
+
+Add *debugfs* integration
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Although frontend drivers provide DVBv5 statistics via the .read_status
+call, a nice addition would be to make additional statistics available to
+userspace via debugfs, which is a simple-to-use, RAM-based filesystem
+specifically designed for debug purposes.
+
+The logic for this would be implemented on a separate file so as not to
+pollute the frontend driver. These statistics are driver-specific and can
+be useful during tests.
+
+The Siano driver is one example of a driver using
+debugfs to convey driver-specific statistics to userspace and it can be
+used as a reference.
+
+This should be further enabled and disabled via a Kconfig
+option for convenience.
+
+Add a way to test video
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently, vidtv can only encode PCM audio. It would be great to implement
+a barebones version of MPEG-2 video encoding so we can also test video. The
+first place to look into is *ISO 13818-2: Information technology — Generic
+coding of moving pictures and associated audio information — Part 2: Video*,
+which covers the encoding of compressed video in MPEG Transport Streams.
+
+This might optionally use the Video4Linux2 Test Pattern Generator, v4l2-tpg,
+which resides at::
+
+ drivers/media/common/v4l2-tpg/
+
+
+Add white noise simulation
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The vidtv tuner already has code to identify whether the chosen frequency
+is too far away from a table of valid frequencies. For now, this means that
+the demodulator can eventually lose the lock on the signal, since the tuner will
+report a bad signal quality.
+
+A nice addition is to simulate some noise when the signal quality is bad by:
+
+- Randomly dropping some TS packets. This will trigger a continuity error if the
+ continuity counter is updated but the packet is not passed on to the demux.
+
+- Updating the error statistics accordingly (e.g. BER, etc).
+
+- Simulating some noise in the encoded data.

+1.1 What the TV decoder can do an what not
+------------------------------------------
+
+The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
+information is not enough. There are several formats of the TV standards.
+And not every TV decoder is able to handle every format. Also the every
+combination is supported by the driver. There are currently 11 different
+tv broadcast formats all aver the world.
+
+The CCIR defines parameters needed for broadcasting the signal.
+The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
+The CCIR says not much about the colorsystem used !!!
+And talking about a colorsystem says not to much about how it is broadcast.
+
+The CCIR standards A,E,F are not used any more.
+
+When you speak about NTSC, you usually mean the standard: CCIR - M using
+the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
+and a few others.
+
+When you talk about PAL, you usually mean: CCIR - B/G using the PAL
+colorsystem which is used in many Countries.
+
+When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
+which is used in France, and a few others.
+
+There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
+Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
+
+The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
+Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
+
+The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
+Ireland, Nigeria, South Africa.
+
+The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
+and is used in Argentinia, Uruguay, an a few others
+
+We do not talk about how the audio is broadcast !
+
+A rather good sites about the TV standards are:
+http://www.sony.jp/support/
+http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
+and http://www.cabl.com/restaurant/channel.html
+
+Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
+used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
+as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
+be the same as NTSC 4.43.
+NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
+to split coma and luma instead of a Delay line.
+
+But I did not defiantly find out what NTSC Comb is.

+What the TV encoder can do an what not
+--------------------------------------
+
+The TV encoder is doing the "same" as the decoder, but in the other direction.
+You feed them digital data and the generate a Composite or SVHS signal.
+For information about the colorsystems and TV norm take a look in the

+
+How do I get this damn thing to work
+------------------------------------
+
+Load zr36067.o. If it can't autodetect your card, use the card=X insmod
+option with X being the card number as given in the previous section.
+To have more than one card, use card=X1[,X2[,X3,[X4[..]]]]
+
+To automate this, add the following to your /etc/modprobe.d/zoran.conf:
+
+options zr36067 card=X1[,X2[,X3[,X4[..]]]]
+alias char-major-81-0 zr36067
+
+One thing to keep in mind is that this doesn't load zr36067.o itself yet. It
+just automates loading. If you start using xawtv, the device won't load on
+some systems, since you're trying to load modules as a user, which is not
+allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to
+XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in
+one of your startup scripts (normally rc.local) if you don't use X. Both
+make sure that the modules are loaded on startup, under the root account.
+
+What mainboard should I use (or why doesn't my card work)
+---------------------------------------------------------
+
+
+<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA.
+
+Experience tells us that people with a Buz, on average, have more problems
+than users with a DC10+/LML33. Also, it tells us that people owning a VIA-
+based mainboard (ktXXX, MVP3) have more problems than users with a mainboard
+based on a different chipset. Here's some notes from Andrew Stevens:
+
+Here's my experience of using LML33 and Buz on various motherboards:
+
+- VIA MVP3
+ - Forget it. Pointless. Doesn't work.
+- Intel 430FX (Pentium 200)
+ - LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie)
+- Intel 440BX (early stepping)
+ - LML33 tolerable. Buz starting to get annoying (6-10 frames/hour)
+- Intel 440BX (late stepping)
+ - Buz tolerable, LML3 almost perfect (occasional single frame drops)
+- SiS735
+ - LML33 perfect, Buz tolerable.
+- VIA KT133(*)
+ - LML33 starting to get annoying, Buz poor enough that I have up.
+
+- Both 440BX boards were dual CPU versions.
+
+Bernhard Praschinger later added:
+
+- AMD 751
+ - Buz perfect-tolerable
+- AMD 760
+ - Buz perfect-tolerable
+
+In general, people on the user mailinglist won't give you much of a chance
+if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd
+rather want to spend some more money on better boards. In general, VIA
+mainboard's IDE/PCI performance will also suck badly compared to others.
+You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview.
+Basically, you can assume that if the Buz works, the LML33 will work too. If
+the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to
+different mainboard chipsets from all of the supported cards.
+
+If you experience timeouts during capture, buy a better mainboard or lower
+the quality/buffersize during capture (see 'Concerning buffer sizes, quality,
+output size etc.'). If it hangs, there's little we can do as of now. Check
+your IRQs and make sure the card has its own interrupts.
+
+Programming interface
+---------------------
+
+This driver conforms to video4linux2. Support for V4L1 and for the custom
+zoran ioctls has been removed in kernel 2.6.38.
+
+For programming example, please, look at lavrec.c and lavplay.c code in
+the MJPEG-tools (http://mjpeg.sf.net/).
+
+Additional notes for software developers:
+
+ The driver returns maxwidth and maxheight parameters according to
+ the current TV standard (norm). Therefore, the software which
+ communicates with the driver and "asks" for these parameters should
+ first set the correct norm. Well, it seems logically correct: TV
+ standard is "more constant" for current country than geometry
+ settings of a variety of TV capture cards which may work in ITU or
+ square pixel format.
+
+Applications

+
+
+Concerning buffer sizes, quality, output size etc.
+--------------------------------------------------
+
+
+The zr36060 can do 1:2 JPEG compression. This is really the theoretical
+maximum that the chipset can reach. The driver can, however, limit compression
+to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz)
+can't handle 1:2 compression without stopping capture after only a few minutes.
+With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into
+1:4 max. compression mode.
+
+100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame
+(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the
+fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 =
+414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT
+(quantization) tables, and you'll get to something like 512kB per frame for
+1:2 compression. For 1:4 compression, you'd have frames of half this size.
+
+Some additional explanation by Martin Samuelsson, which also explains the
+importance of buffer sizes:
+--
+> Hmm, I do not think it is really that way. With the current (downloaded
+> at 18:00 Monday) driver I get that output sizes for 10 sec:
+> -q 50 -b 128 : 24.283.332 Bytes
+> -q 50 -b 256 : 48.442.368
+> -q 25 -b 128 : 24.655.992
+> -q 25 -b 256 : 25.859.820
+
+I woke up, and can't go to sleep again. I'll kill some time explaining why
+this doesn't look strange to me.
+
+Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
+actually use that number or not, but that's not too important right now.
+
+704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
+3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
+1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
+output becomes 512 bits per block. Actually 510, but 512 is simpler to use
+for calculations.
+
+Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
+becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
+here, so we don't need to do any fancy corrections for bits-per-pixel or such
+things. 101376 bytes per field.
+
+d1 video contains two fields per frame. Those sum up to 202752 bytes per
+frame, and one of those frames goes into each buffer.
+
+But wait a second! -b128 gives 128kB buffers! It's not possible to cram
+202752 bytes of JPEG data into 128kB!
+
+This is what the driver notice and automatically compensate for in your
+examples. Let's do some math using this information:
+
+128kB is 131072 bytes. In this buffer, we want to store two fields, which
+leaves 65536 bytes for each field. Using 3168 blocks per field, we get
+20.68686868... available bytes per block; 165 bits. We can't allow the
+request for 256 bits per block when there's only 165 bits available! The -q50
+option is silently overridden, and the -b128 option takes precedence, leaving
+us with the equivalence of -q32.
+
+This gives us a data rate of 165 bits per block, which, times 3168, sums up
+to 65340 bytes per field, out of the allowed 65536. The current driver has
+another level of rate limiting; it won't accept -q values that fill more than
+6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
+a safe bet. Personally, I think I would have lowered requested-bits-per-block
+by one, or something like that.) We can't use 165 bits per block, but have to
+lower it again, to 6/8 of the available buffer space: We end up with 124 bits
+per block, the equivalence of -q24. With 128kB buffers, you can't use greater
+than -q24 at -d1. (And PAL, and 704 pixels width...)
+
+The third example is limited to -q24 through the same process. The second
+example, using very similar calculations, is limited to -q48. The only
+example that actually grab at the specified -q value is the last one, which
+is clearly visible, looking at the file size.
+--
+
+Conclusion: the quality of the resulting movie depends on buffer size, quality,
+whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
+module to do 1:4 instead of 1:2 compression, etc.
+
+If you experience timeouts, lowering the quality/buffersize or using
+'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
+proven by the Buz.
+
+It hangs/crashes/fails/whatevers! Help!
+---------------------------------------
+
+Make sure that the card has its own interrupts (see /proc/interrupts), check
+the output of dmesg at high verbosity (load zr36067.o with debug=2,
+load all other modules with debug=1). Check that your mainboard is favorable
+(see question 2) and if not, test the card in another computer. Also see the
+notes given in question 3 and try lowering quality/buffersize/capturesize
+if recording fails after a period of time.
+
+If all this doesn't help, give a clear description of the problem including
+detailed hardware information (memory+brand, mainboard+chipset+brand, which
+MJPEG card, processor, other PCI cards that might be of interest), give the
+system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
+the kernel version, driver version, glibc version, gcc version and any other
+information that might possibly be of interest. Also provide the dmesg output
+at high verbosity. See 'Contacting' on how to contact the developers.

+ :term:`SoC` or :term:`FPGA`.
+
+ Hardware Peripheral
+ A group of :term:`hardware components <Hardware Component>` that
+ together make a larger user-facing functional peripheral. For
+ instance, the :term:`SoC` :term:`ISP` :term:`IP Block`
+ and the external camera sensors together make a camera hardware
+ peripheral.
+
+ Also known as :term:`Peripheral`.
+
+ I²C

+ semiconductor material, normally silicon.
+
+ Also known as chip.
+
+ IP Block
+ **Intellectual property core**
+
+ In electronic design a semiconductor intellectual property core,
+ is a reusable unit of logic, cell, or integrated circuit layout
+ design that is the intellectual property of one party.
+ IP Blocks may be licensed to another party or can be owned
+ and used by a single party alone.
+
+ See https://en.wikipedia.org/wiki/Semiconductor_intellectual_property_core).
+
+ ISP
+ **Image Signal Processor**
+
+ A specialized processor that implements a set of algorithms for
+ processing image data. ISPs may implement algorithms for lens
+ shading correction, demosaicing, scaling and pixel format conversion
+ as well as produce statistics for the use of the control
+ algorithms (e.g. automatic exposure, white balance and focus).
+
+ Media API
+ A set of userspace APIs used to control the media hardware. It is
+ composed by:
+
+ - :term:`CEC API`;

-Device Naming
-=============
+Controlling a hardware peripheral via V4L2
+==========================================
+
+Hardware that is supported using the V4L2 uAPI often consists of multiple
+devices or peripherals, each of which have their own driver.
+
+The bridge driver exposes one or more V4L2 device nodes
+(see :ref:`v4l2_device_naming`).
+
+There are other drivers providing support for other components of
+the hardware, which may also expose device nodes, called V4L2 sub-devices.
+
+When such V4L2 sub-devices are exposed, they allow controlling those
+other hardware components - usually connected via a serial bus (like
+I²C, SMBus or SPI). Depending on the bridge driver, those sub-devices
+can be controlled indirectly via the bridge driver or explicitly via
+the :ref:`Media Controller <media_controller>` and via the
+:ref:`V4L2 sub-devices <subdev>`.
+
+The devices that require the use of the
+:ref:`Media Controller <media_controller>` are called **MC-centric**
+devices. The devices that are fully controlled via V4L2 device nodes
+are called **video-node-centric**.
+
+Userspace can check if a V4L2 hardware peripheral is MC-centric by
+calling :ref:`VIDIOC_QUERYCAP` and checking the
+:ref:`device_caps field <device-capabilities>`.
+
+If the device returns ``V4L2_CAP_IO_MC`` flag at ``device_caps``,
+then it is MC-centric, otherwise, it is video-node-centric.
+
+It is required for MC-centric drivers to identify the V4L2
+sub-devices and to configure the pipelines via the
+:ref:`media controller API <media_controller>` before using the peripheral.
+Also, the sub-devices' configuration shall be controlled via the
+:ref:`sub-device API <subdev>`.
+
+.. note::
+
+ A video-node-centric may still provide media-controller and
+ sub-device interfaces as well.
+
+ However, in that case the media-controller and the sub-device
+ interfaces are read-only and just provide information about the
+ device. The actual configuration is done via the video nodes.

+Configuration parameters
+========================
+
+The configuration parameters are passed to the
+:ref:`rkisp1_params <rkisp1_params>` metadata output video node, using
+the :c:type:`v4l2_meta_format` interface. The buffer contains
+a single instance of the C structure :c:type:`rkisp1_params_cfg` defined in
+``rkisp1-config.h``. So the structure can be obtained from the buffer by:
+
+.. code-block:: c

+
+.. rkisp1_stat_buffer
+
+3A and histogram statistics
+===========================
+
+The ISP1 device collects different statistics over an input Bayer frame.
+Those statistics are obtained from the :ref:`rkisp1_stats <rkisp1_stats>`
+metadata capture video node,
+using the :c:type:`v4l2_meta_format` interface. The buffer contains a single
+instance of the C structure :c:type:`rkisp1_stat_buffer` defined in
+``rkisp1-config.h``. So the structure can be obtained from the buffer by:
+
+.. code-block:: c
+
+ struct rkisp1_stat_buffer *stats = (struct rkisp1_stat_buffer*) buffer;
+
+The statistics collected are Exposure, AWB (Auto-white balance), Histogram and
+AF (Auto-focus). See :c:type:`rkisp1_stat_buffer` for details of the statistics.
+
+The 3A statistics and configuration parameters described here are usually
+consumed and produced by dedicated user space libraries that comprise the

TODO list
-* Currently driver supports Tegra build-in TPG only with direct media links
- from CSI to VI. Add kernel config CONFIG_VIDEO_TEGRA_TPG and update the
- driver to do TPG Vs Sensor media links based on CONFIG_VIDEO_TEGRA_TPG.
-* Add real camera sensor capture support.
-* Add Tegra CSI MIPI pads calibration.
-* Add MIPI clock Settle time computation based on the data rate.
* Add support for Ganged mode.
* Add RAW10 packed video format support to Tegra210 video formats.
* Add support for suspend and resume.

- *
- * This module is part of usbvision driver project.
- *
- * Let's call the version 0.... until compression decoding is completely

- *
- * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
- * It was based on USB CPiA driver written by Peter Pregler,
- * Scott J. Bertin and Johannes Erdfelt
- * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
- * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
- * Updates to driver completed by Dwaine P. Garden
- *
- * TODO:
- * - use submit_urb for all setup packets
- * - Fix memory settings for nt1004. It is 4 times as big as the
- * nt1003 memory.
- * - Add audio on endpoint 3 for nt1004 chip.
- * Seems impossible, needs a codec interface. Which one?
- * - Clean up the driver.
- * - optimization for performance.
- * - Add Videotext capability (VBI). Working on it.....
- * - Check audio for other devices

+/* =================== */
+
+/* Should ease the (re-)usage of drivers supporting cards with (different)
+ video codecs. The codecs register to this module their functionality,
+ and the processors (masters) can attach to them if they fit.
+
+ The codecs are typically have a "strong" binding to their master - so I
+ don't think it makes sense to have a full blown interfacing as with e.g.
+ i2c. If you have an other opinion, let's discuss & implement it :-)))
+
+ Usage:
+
+ The slave has just to setup the videocodec structure and use two functions:
+ videocodec_register(codecdata);
+ videocodec_unregister(codecdata);
+ The best is just calling them at module (de-)initialisation.
+
+ The master sets up the structure videocodec_master and calls:
+ codecdata=videocodec_attach(master_codecdata);
+ videocodec_detach(codecdata);
+
+ The slave is called during attach/detach via functions setup previously
+ during register. At that time, the master_data pointer is set up
+ and the slave can access any io registers of the master device (in the case
+ the slave is bound to it). Otherwise it doesn't need this functions and
+ therfor they may not be initialized.
+
+ The other functions are just for convenience, as they are for sure used by
+ most/all of the codecs. The last ones may be omitted, too.
+
+ See the structure declaration below for more information and which data has
+ to be set up for the master and the slave.
+
+ ----------------------------------------------------------------------------
+ The master should have "knowledge" of the slave and vice versa. So the data
+ structures sent to/from slave via set_data/get_data set_image/get_image are
+ device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

+/*
+ ==== master setup ====
+ name -> name of the device structure for reference and debugging
+ master_data -> data ref. for the master (e.g. the zr36055,57,67)
+ readreg -> ref. to read-fn from register (setup by master, used by slave)
+ writereg -> ref. to write-fn to register (setup by master, used by slave)
+ this two functions do the lowlevel I/O job
+
+ ==== slave functionality setup ====
+ slave_data -> data ref. for the slave (e.g. the zr36050,60)
+ check -> fn-ref. checks availability of an device, returns -EIO on failure or
+ the type on success
+ this makes espcecially sense if a driver module supports more than
+ one codec which may be quite similar to access, nevertheless it
+ is good for a first functionality check
+
+ -- main functions you always need for compression/decompression --
+
+ set_mode -> this fn-ref. resets the entire codec, and sets up the mode
+ with the last defined norm/size (or device default if not
+ available) - it returns 0 if the mode is possible
+ set_size -> this fn-ref. sets the norm and image size for
+ compression/decompression (returns 0 on success)
+ the norm param is defined in videodev2.h (V4L2_STD_*)
+
+ additional setup may be available, too - but the codec should work with
+ some default values even without this
+
+ set_data -> sets device-specific data (tables, quality etc.)
+ get_data -> query device-specific data (tables, quality etc.)
+
+ if the device delivers interrupts, they may be setup/handled here
+ setup_interrupt -> codec irq setup (not needed for 36050/60)
+ handle_interrupt -> codec irq handling (not needed for 36050/60)
+
+ if the device delivers pictures, they may be handled here
+ put_image -> puts image data to the codec (not needed for 36050/60)
+ get_image -> gets image data from the codec (not needed for 36050/60)
+ the calls include frame numbers and flags (even/odd/...)
+ if needed and a flag which allows blocking until its ready
