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

Module Parameters
|
||||
-----------------
|
||||
|
||||
force_addr=0xaddr Set the I/O base address. Useful for boards
|
||||
that don't set the address in the BIOS. Does not do a
|
||||
PCI force; the device must still be present in lspci.
|
||||
Don't use this unless the driver complains that the
|
||||
base address is not set.
|
||||
Example: 'modprobe i2c-ali15x3 force_addr=0xe800'
|
||||
* force_addr: int
|
||||
Initialize the base address of the i2c controller
