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