Description
-----------

This is the driver for the SMB Host controller on
Acer Labs Inc. (ALI) M1535 South Bridge.

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

The SMB controller is part of the 7101 device, which is an
ACPI-compliant Power Management Unit (PMU).

The whole 7101 device has to be enabled for the SMB to work.
You can't just enable the SMB alone.
The SMB and the ACPI have separate I/O spaces.
We make sure that the SMB is enabled. We leave the ACPI alone.


Features
--------

This driver controls the SMB Host only.
This driver does not use interrupts.
