0018 Description
0019 -----------
0020
0021 This is the driver for the SMB Host controller on Acer Labs Inc. (ALI)
0022 M1535 South Bridge.
0023
0024 The M1535 is a South bridge for portable systems. It is very similar to the
0025 M15x3 South bridges also produced by Acer Labs Inc. Some of the registers
0026 within the part have moved and some have been redefined slightly.
0027 Additionally, the sequencing of the SMBus transactions has been modified to
0028 be more consistent with the sequencing recommended by the manufacturer and
0029 observed through testing. These changes are reflected in this driver and
0030 can be identified by comparing this driver to the i2c-ali15x3 driver. For
0031 an overview of these chips see http://www.acerlabs.com
0032
0033 The SMB controller is part of the M7101 device, which is an ACPI-compliant
0034 Power Management Unit (PMU).
0035
0036 The whole M7101 device has to be enabled for the SMB to work. You can't
0037 just enable the SMB alone. The SMB and the ACPI have separate I/O spaces.
0038 We make sure that the SMB is enabled. We leave the ACPI alone.

0041 Features
0042 --------
0043
0044 This driver controls the SMB Host only. This driver does not use
0045 interrupts.
