| Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for |
| a general description of GPIO and interrupt bindings. |
| |
| Please refer to pinctrl-bindings.txt in this directory for details of the |
| common pinctrl bindings used by client devices, including the meaning of the |
| phrase "pin configuration node". |
| |
| The pin configuration nodes act as a container for an arbitrary number of |
| subnodes. Each of these subnodes represents some desired configuration for a |
| pin, a group, or a list of pins or groups. This configuration can include the |
| mux function to select on those pin(s)/group(s), and various pin configuration |
| parameters, such as pull-up, drive strength, etc. |
| |
| |
| PIN CONFIGURATION NODES: |
| |
| The name of each subnode is not important; all subnodes should be enumerated |
| and processed purely based on their content. |
| |
| Each subnode only affects those parameters that are explicitly listed. In |
| other words, a subnode that lists a mux function but no pin configuration |
| parameters implies no information about any pin configuration parameters. |
| Similarly, a pin subnode that describes a pullup parameter implies no |
| information about e.g. the mux function. |
| |
| |
| The following generic properties as defined in pinctrl-bindings.txt are valid |
| to specify in a pin configuration subnode: |
| |
| - pins: |
| Usage: required |
| Value type: <string-array> |
| Definition: List of gpio pins affected by the properties specified in |
| this subnode. |
| |
| Valid pins are: |
| gpio0-gpio149 |

| |
| sdc1_clk, sdc1_cmd, sdc1_data sdc2_clk, sdc2_cmd, |
| sdc2_data sdc1_rclk |
| Supports bias and drive-strength |
| |
