Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.

41This driver controls the SMB Host only. This driver does not use
42interrupts.
