18Description
19-----------
20
21This is the driver for the SMB Host controller on Acer Labs Inc. (ALI)
22M1535 South Bridge.
23
24The M1535 is a South bridge for portable systems. It is very similar to the
25M15x3 South bridges also produced by Acer Labs Inc.  Some of the registers
26within the part have moved and some have been redefined slightly.
27Additionally, the sequencing of the SMBus transactions has been modified to
28be more consistent with the sequencing recommended by the manufacturer and
29observed through testing.  These changes are reflected in this driver and
30can be identified by comparing this driver to the i2c-ali15x3 driver. For
31an overview of these chips see http://www.acerlabs.com

33The SMB controller is part of the M7101 device, which is an ACPI-compliant
34Power Management Unit (PMU).
35
36The whole M7101 device has to be enabled for the SMB to work. You can't
37just enable the SMB alone. The SMB and the ACPI have separate I/O spaces.
38We make sure that the SMB is enabled. We leave the ACPI alone.
