48Module Parameters
49-----------------
50
51==================	=====================================================
52force_addr=0xaddr	Set the I/O base address. Useful for boards
53			that don't set the address in the BIOS. Does not do a
54			PCI force; the device must still be present in lspci.
55			Don't use this unless the driver complains that the
56			base address is not set.

59Description
60-----------
61
62i2c-sis5595 is a true SMBus host driver for motherboards with the SiS5595
63southbridges.
64
65WARNING: If you are trying to access the integrated sensors on the SiS5595
66chip, you want the sis5595 driver for those, not this driver. This driver
67is a BUS driver, not a CHIP driver. A BUS driver is used by other CHIP
68drivers to access chips on the bus.
