Description |

This is the driver for the SMB Host controller on |
|---|
| 27 |
Acer Labs Inc. (ALI) M1535 South Bridge. |
|---|
| 28 |
|
|---|
| 29 |
The M1535 is a South bridge for portable systems. |
|---|
| 30 |
It is very similar to the M15x3 South bridges also produced |
|---|
| 31 |
by Acer Labs Inc. Some of the registers within the part |
|---|
| 32 |
have moved and some have been redefined slightly. Additionally, |
|---|
| 33 |
the sequencing of the SMBus transactions has been modified |
|---|
| 34 |
to be more consistent with the sequencing recommended by |
|---|
| 35 |
the manufacturer and observed through testing. These |
|---|
| 36 |
changes are reflected in this driver and can be identified |
|---|
| 37 |
by comparing this driver to the i2c-ali15x3 driver. |
|---|

The SMB controller is part of the 7101 device, which is an |
|---|
| 41 |
ACPI-compliant Power Management Unit (PMU). |
|---|
| 42 |
|
|---|
| 43 |
The whole 7101 device has to be enabled for the SMB to work. |
|---|
| 44 |
You can't just enable the SMB alone. |
|---|
| 45 |
The SMB and the ACPI have separate I/O spaces. |
|---|
| 46 |
We make sure that the SMB is enabled. We leave the ACPI alone. |
