(ALI) 22M1535 South Bridge. 23 24The M1535 is a South bridge for portable systems. It is very similar to the 25M15x3 South bridges also produced by Acer Labs Inc. Some of the registers 26within the part have moved and some have been redefined slightly. 27Additionally, the sequencing of the SMBus transactions has been modified to 28be more consistent with the sequencing recommended by the manufacturer and 29observed through testing. These changes are reflected in this driver and 30can be identified by comparing this driver to the i2c-ali15x3 driver. For 31an overview of these chips see http://www.acerlabs.com 32 33The SMB controller is part of the M7101 device, which is an ACPI-compliant 34Power Management Unit (PMU). 35 36The whole M7101 device has to be enabled for the SMB to work. You can't 37just enable the SMB alone. The SMB and the ACPI have separate I/O spaces. 38We make sure that the SMB is enabled. We leave the ACPI alone. 39 40 41Features 42-------- 43 44This driver controls the SMB Host only. This driver does not use 45interrupts. 46
