1Kernel driver i2c-ali1535 2 3Supported adapters: 4 * Acer Labs, Inc. ALI 1535 (south bridge) 5 Datasheet: Now under NDA 6 http://www.ali.com.tw/eng/support/datasheet_request.php 7 8Authors: 9 Frodo Looijaard <email@example.com>, 10 Philip Edelbrock <firstname.lastname@example.org>, 11 Mark D. Studebaker <email@example.com>, 12 Dan Eaton <firstname.lastname@example.org>, 13 Stephen Rousset<email@example.com> 14 15Description 16----------- 17 18This is the driver for the SMB Host controller on Acer Labs Inc. (ALI) 19M1535 South Bridge. 20 21The M1535 is a South bridge for portable systems. It is very similar to the 22M15x3 South bridges also produced by Acer Labs Inc. Some of the registers 23within the part have moved and some have been redefined slightly. 24Additionally, the sequencing of the SMBus transactions has been modified to 25be more consistent with the sequencing recommended by the manufacturer and 26observed through testing. These changes are reflected in this driver and 27can be identified by comparing this driver to the i2c-ali15x3 driver. For 28an overview of these chips see http://www.acerlabs.com 29 30The SMB controller is part of the M7101 device, which is an ACPI-compliant 31Power Management Unit (PMU). 32 33The whole M7101 device has to be enabled for the SMB to work. You can't 34just enable the SMB alone. The SMB and the ACPI have separate I/O spaces. 35We make sure that the SMB is enabled. We leave the ACPI alone. 36 37 38Features 39-------- 40 41This driver controls the SMB Host only. This driver does not use 42interrupts.
