7 Any combination of these host bridges:
8 645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746

17 This SMBus only driver is known to work on motherboards with the above
18 named chipset combinations. The driver was developed without benefit of a
19 proper datasheet from SiS. The SMBus registers are assumed compatible with
20 those of the SiS630, although they are located in a completely different
21 place. Thanks to Alexander Malysh <amalysh@web.de> for providing the
22 SiS630 datasheet (and driver).
24 The command "lspci" as root should produce something like these lines:
26 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
27 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
28 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
32 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
33 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961
34 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
36 (kernel versions later than 2.4.18 may fill in the "Unknown"s)
38 If you can't see it please look on quirk_sis_96x_smbus
39 (drivers/pci/quirks.c) (also if southbridge detection fails)
41 I suspect that this driver could be made to work for the following SiS
42 chipsets as well: 635, and 635T. If anyone owns a board with those chips
43 AND is willing to risk crashing & burning an otherwise well-behaved kernel
44 in the name of progress... please contact me at <mhoffman@lightlink.com> or
45 via the linux-i2c mailing list: <linux-i2c@vger.kernel.org>. Please send bug
46 reports and/or success stories as well.
52 * The driver does not support SMBus block reads/writes; I may add them if a
53 scenario is found where they're needed.
