| Kernel driver i2c-sis96x | |
| ======================== | |
| Replaces 2.4.x i2c-sis645 | |
| Supported adapters: | |
| * Silicon Integrated Systems Corp (SiS) | |
| Any combination of these host bridges: | |
| 645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746 | |
| and these south bridges: | |
| 961, 962, 963(L) | |

| Description | |
| ----------- | |
| This SMBus only driver is known to work on motherboards with the above | |
| named chipset combinations. The driver was developed without benefit of a | |
| proper datasheet from SiS. The SMBus registers are assumed compatible with | |
| those of the SiS630, although they are located in a completely different | |
| place. Thanks to Alexander Malysh <amalysh@web.de> for providing the | |
| SiS630 datasheet (and driver). | |
| The command ``lspci`` as root should produce something like these lines:: | |
| 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 | |
| 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 | |
| 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | |
| or perhaps this:: | |
| 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 | |
| 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961 | |
| 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | |
| (kernel versions later than 2.4.18 may fill in the "Unknown"s) | |
| If you can't see it please look on quirk_sis_96x_smbus | |
| (drivers/pci/quirks.c) (also if southbridge detection fails) | |
| I suspect that this driver could be made to work for the following SiS | |
| chipsets as well: 635, and 635T. If anyone owns a board with those chips | |
| AND is willing to risk crashing & burning an otherwise well-behaved kernel | |
| in the name of progress... please contact me at <mhoffman@lightlink.com> or | |
| via the linux-i2c mailing list: <linux-i2c@vger.kernel.org>. Please send bug | |
| reports and/or success stories as well. | |
| TO DOs | |
| ------ | |
| * The driver does not support SMBus block reads/writes; I may add them if a | |
| scenario is found where they're needed. | |
| Thank You | |
