- 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.
