51*4882a593Smuzhiyun==================	=====================================================
52*4882a593Smuzhiyunforce_addr=0xaddr	Set the I/O base address. Useful for boards
53*4882a593Smuzhiyun			that don't set the address in the BIOS. Does not do a
54*4882a593Smuzhiyun			PCI force; the device must still be present in lspci.
55*4882a593Smuzhiyun			Don't use this unless the driver complains that the
56*4882a593Smuzhiyun			base address is not set.

59*4882a593SmuzhiyunDescription
60*4882a593Smuzhiyun-----------
61*4882a593Smuzhiyun
62*4882a593Smuzhiyuni2c-sis5595 is a true SMBus host driver for motherboards with the SiS5595
63*4882a593Smuzhiyunsouthbridges.
64*4882a593Smuzhiyun
65*4882a593SmuzhiyunWARNING: If you are trying to access the integrated sensors on the SiS5595
66*4882a593Smuzhiyunchip, you want the sis5595 driver for those, not this driver. This driver
67*4882a593Smuzhiyunis a BUS driver, not a CHIP driver. A BUS driver is used by other CHIP
68*4882a593Smuzhiyundrivers to access chips on the bus.
