| 19 | Description | |
| 20 | ----------- | |
| 21 | ||
| 22 | This SMBus only driver is known to work on motherboards with the above | |
| 23 | named chipset combinations. The driver was developed without benefit of a | |
| 24 | proper datasheet from SiS. The SMBus registers are assumed compatible with | |
| 25 | those of the SiS630, although they are located in a completely different | |
| 26 | place. Thanks to Alexander Malysh <amalysh@web.de> for providing the | |
| 27 | SiS630 datasheet (and driver). | |
| 28 | ||
| ccf988b6 | 29 | The command ``lspci`` as root should produce something like these lines:: |
| 1da177e4 | 30 | |
| ccf988b6 MCC |
31 | 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 |
| 32 | 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 | |
| 33 | 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | |
| 1da177e4 | 34 | |
| ccf988b6 | 35 | or perhaps this:: |
| 1da177e4 | 36 | |
| ccf988b6 MCC |
37 | 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 |
| 38 | 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961 | |
| 39 | 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 | |

| 41 | (kernel versions later than 2.4.18 may fill in the "Unknown"s) | |

| 25985edc | 43 | If you can't see it please look on quirk_sis_96x_smbus |
| 1da177e4 LT |
44 | (drivers/pci/quirks.c) (also if southbridge detection fails) |
| 45 | ||
| 46 | I suspect that this driver could be made to work for the following SiS | |
| 47 | chipsets as well: 635, and 635T. If anyone owns a board with those chips | |
| 48 | AND is willing to risk crashing & burning an otherwise well-behaved kernel | |
| 49 | in the name of progress... please contact me at <mhoffman@lightlink.com> or | |
| 846557d3 | 50 | via the linux-i2c mailing list: <linux-i2c@vger.kernel.org>. Please send bug |
| 5d925fec | 51 | reports and/or success stories as well. |

| 54 | TO DOs | |
| 55 | ------ | |
| 56 | ||
| 57 | * The driver does not support SMBus block reads/writes; I may add them if a | |
| ccf988b6 | 58 | scenario is found where they're needed. |
