platform/x86: drop deprecated asus_acpi driver

2012-03-20T16:02:18+00:00

asus_acpi only support old models, it has been deprecated since
2009 in favor of asus-laptop, it's not built by any (sane) distro,
so it is time to say good bye.

Thanks to Julien Lerouge and Karol Kozimor for the work they have
done on it, I would never have wrote asus-laptop and other asus
related drivers without asus_acpi.

acpi: add export.h to files using THIS_MODULE/EXPORT_SYMBOL

2011-10-31T23:30:34+00:00

These files were relying on module.h to come in via the path
in an include/acpi header file, but we don't want to have
instances of module.h being included from include/* files
if it can be avoided.  Have the files include export.h instead.

ACPI / Video: Probe for output switch method when searching video devices.

2011-02-12T00:40:16+00:00

This patch reverts one hunk of 677bd810eedce61edf15452491781ff046b92edc
"ACPI video: remove output switching control", namely the removal of
probing for _DOS/_DOD when searching for video devices.

This is needed on some Fujitsu Laptops (at least S7110, P8010) for the
ACPI backlight interface to work, as an these machines, neither ROM nor
posting methods are available, and after removal of output switching,
none of the caps triggers, which prevents the backlight search from
being entered.

Tested on a Fujitsu Lifebook S7110 and Fujitsu Lifebook P8010.
This probably fixes https://bugzilla.kernel.org/show_bug.cgi?id=27312
for the people who have no entry in /sys/class/backlight.

This is the complete list of public (starting with "_") methods implemented
on the S7110, BIOS rev 1.34:

\_SB_.PCI0.GFX0._ADR
\_SB_.PCI0.GFX0._DOS
\_SB_.PCI0.GFX0._DOD
\_SB_.PCI0.GFX0.CRT._ADR
\_SB_.PCI0.GFX0.CRT._DCS
\_SB_.PCI0.GFX0.CRT._DGS

\_SB_.PCI0.GFX0.LCD._DSS

\_SB_.PCI0.GFX0.LCD._PS3
\_SB_.PCI0.GFX0.TV._ADR

ACPI video: remove output switching control

2010-12-14T05:04:52+00:00

Remove the ACPI video output switching control as it never works.

With the patch applied,
ACPI video driver still catches the video output notification,
but it does nothing but raises the notification to userspace.

ACPICA: Add post-order callback to acpi_walk_namespace

2009-11-25T02:31:10+00:00

The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779.

Also update the external calls to acpi_walk_namespace.

ACPI: video: Loosen strictness of video bus detection code

2009-10-13T06:50:38+00:00

BugLink: http://bugs.launchpad.net/bugs/333386

Currently a video bus device must (beside other criteria) define _DOD and
_DOS methods to be considered a video device.
Some broken BIOSes prevented working backlight control by only defining both
for one (non-existing bus) and only _DOD for the rest. With this patch in
place the other bus definitions were considered too and backlight control
started to work again.
