| 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 cant 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.
