(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. |
