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 M7101 device, which is an ACPI-compliant
|
||
|
|
Power Management Unit (PMU).
|
||
|
|
|
||
|
|
The whole M7101 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.
