The ACPI video module provides two functionalities: backlight control
and backlight hotkey event delivery. It is possible the backlight
control interface is broken while the system still needs its event
delivery, so it's worth to seperate the two interfaces clearly.
This patchset has two patches,
The backlight control and event delivery functionality provided by ACPI
video module is mixed together and registered all during video device
enumeration time. As a result, the two functionality are also removed
together on module unload time or by the acpi_video_unregister function.
The two functi
According to Matthew Garrett, "Windows 8 leaves backlight control up
to individual graphics drivers rather than making ACPI calls itself.
There's plenty of evidence to suggest that the Intel driver for
Windows [8] doesn't use the ACPI interface, including the fact that
it's broken on a bunch of mac

Hi Aaaron,
Have we grown any clue meanwhile about which Intel boxes need this and for
which we still need to keep the acpi backlight around? I've grown _very_
reluctant to just adding tons of quirks to our driver for the backlight.
Almost all the quirks we have added recently (or that have been pr

First of all, there is a bunch of boxes where ACPI backlight works incorrectly

Three patches are included, reviewed by Haihao, Xiang.

From: Mengdong Lin
The PCH transcoder config register (PCH_TRANS_CONF, 0xf0008) is not the
correct config register for transcoder A, B or C. This register is in
PCH and for CRT display, nothing to do with display audio.
So This patch removes misuse of it as config register for transcoder A/B/C.
From: Mengdong Lin
For Haswell, some audio configuration registers have changed their name and
some bit definitions.
This patch applies the changes, and uses subfunctions to parse registers for
code reuse.
Here is the name change list:
Audio configuration: AUD_CONFIG_x to AUD_TCx_CONFIG

The hex number should be shown with zero stuffed instead of spaces.
