    21     This is the driver for the SMB Host controller on

    24     The M1535 is a South bridge for portable systems. 
    25     It is very similar to the M15x3 South bridges also produced 
    26     by Acer Labs Inc.  Some of the registers within the part 
    27     have moved and some have been redefined slightly. Additionally, 
    28     the sequencing of the SMBus transactions has been modified 
    29     to be more consistent with the sequencing recommended by 
    30     the manufacturer and observed through testing.  These 
    31     changes are reflected in this driver and can be identified 
    32     by comparing this driver to the i2c-ali15x3 driver. 
    33     For an overview of these chips see http://www.acerlabs.com

    17 force_addr=0xaddr       Set the I/O base address. Useful for boards 
    18                         that don't set the address in the BIOS. Does not do a 
    19                         PCI force; the device must still be present in lspci. 
    20                         Don't use this unless the driver complains that the 
    21                         base address is not set. 
    22                         Example: 'modprobe i2c-ali15x3 force_addr=0xe800'
