Hoffman <mhoffman@lightlink.com>18 19Description20-----------21 22This SMBus only driver is known to work on motherboards with the above23named chipset combinations. The driver was developed without benefit of a24proper datasheet from SiS. The SMBus registers are assumed compatible with25those of the SiS630, although they are located in a completely different26place. Thanks to Alexander Malysh <amalysh@web.de> for providing the27SiS630 datasheet (and driver).28 29The command ``lspci`` as root should produce something like these lines::30 31 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 064532 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/551333 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 001634 35or perhaps this::36 37 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 064538 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 096139 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 001640 41(kernel versions later than 2.4.18 may fill in the "Unknown"s)42 43If you can't see it please look on quirk_sis_96x_smbus44(drivers/pci/quirks.c) (also if southbridge detection fails)45 46I suspect that this driver could be made to work for the following SiS47chipsets as well: 635, and 635T. If anyone owns a board with those chips48AND is willing to risk crashing & burning an otherwise well-behaved kernel49in the name of progress... please contact me at <mhoffman@lightlink.com> or50via the linux-i2c mailing list: <linux-i2c@vger.kernel.org>. Please send bug51reports and/or success stories as well.52 53 54TO DOs55------56 57* The driver does not support SMBus block reads/writes; I may add them if a58 scenario is found where they're needed.59 60 61Thank You62---------63 64Mark D.
