(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. + +Stability +--------- +Beta. + + +Supported Devices +----------------- +Acer Labs Inc.
