Convert the backlight and LCD classes from struct class_device
to struct device since class_device is scheduled for removal.
One nasty API break is the backlight power attribute has had to be
renamed to bl_power and the LCD power attribute has had to be renamed
to lcd_power since the original names clash with the core. I can't see
a way around this.

Switch the order of LCD_CLASS_DEVICE and BACKLIGHT_CLASS_DEVICE,
so that it's possible to insert LCD devices without borking the

The file name is the signature, such as DSDT,
and the contents are the binary table image.
Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3
All static tables (besides teh RSDP and RSDT themselves
are exported. Dynamic tables, such as SSDT op-regions that
are not declared in the RSDT, will be added in a subsequent patch.

In Linux-2.6.22 we expanded the boot parameter osi=
so that it can enable and !enable an OSI string.
_OSI(Linux) is a special case because we know that there
are both systems that require it set, and systems
require that it _not_ to be set. In the long term it can't
be set, for the same reason _OS(Linux) can't be enabled --
it tends to confuse BIOS that are not properly
validated with Linux. Further, the semantics and version
information of _OSI(Linux) were never actually defined.
The kernel prints out a message if it sees _OSI(Linux)
requested, and there is a DMI workaround to invoke
"osi=Linux" automatically for existing systems that need it.

Currently the acpi video module export the backlight interface to sysfs
also if acpi_video_device_lcd_query_levels() fails to read _BLC method
(e.g. because the method is not available). In this case the userspace
don't know which brightness level are supported and can't set a brightness
level (echo return with: "write error: Invalid Argument"). This happend
e.g. on a ASUS RF1 (correct supported by the asus-laptop module).
The video module should not export the backlight interface if query _BLC fail,
because you can't set anything from userspace and this make it useless.

Requires CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO.
After loading output.ko and video.ko, you would have
/sys/class/video_output and several device acpi_videoNum there.
For example, I got acpi_video0, acpi_video1,acpi_video2,and acpi_video3
under /sys/class/video_output on my T40.
I can query the status of output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device). Also you can turn off video1 and turn on
video0 by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC B.5.7 _DSS for the parameter definition.
Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.
the driver output.ko and video.ko just works like a interface to
invoke BIOS.

The backlight class does all the locking needed for sysfs access, but
offers no API to interface to that locking without an layer violation.
Since we need to mutex-lock procfs access, implement in-driver locking for
brightness. It will go away the day thinkpad-acpi procfs goes away, or the
backlight class gives us a way to use its locks without a layer violation.

We get +128 instead of -128 from the DSDT TMPx methods, due to errors when
converting a EC byte return that is a s8 to an ACPI handler return that is
an int.
Fix it once and for all, by clamping acceptable temperature readings from
DSDT TMPx so that anything outside the [-127,+127] range is converted to
TP_EC_THERMAL_TMP_NA (-128).

Lenovo ThinkPads have a slightly different key map layout from IBM
ThinkPads (fn+f2 and fn+f3 are swapped). Knowing which one we are dealing
with, we can properly set a few more hot keys up by default.
Also, export the correct vendor in the input device, as that information
might be useful to userspace.

It appears that Lenovo decided to break the EC brightness control interface
in a weird way in their latest BIOSes. Fortunately, the old CMOS NVRAM
interface works just fine in such BIOSes.
Add a module parameter that allows the user to select which strategy to use
for brightness control: EC, NVRAM, or both. By default, do both (which is
the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use
NVRAM only on Lenovo ThinkPads.

Make the input layer the default way to deal with thinkpad-acpi hot keys,
but add a kernel config option to retain the old way of doing things.
This means we map a lot more keys to useful stuff by default, and also that
we enable hot key handling by default on driver load (like Windows does).
The documentation for proper use of this resource is also updated.

Add input device support to the hotkey subdriver.
Hot keys that have a valid keycode mapping are reported through the input
layer if the input device is open. Otherwise, they will be reported as
ACPI events, as they were before.
Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY
KEY_UNKNOWN events.
For backwards compatibility purposes, hot keys that used to be reported
through ACPI events are not mapped to anything meaningful by default.
Userspace is supposed to remap them if it wants to use the input device for
hot key reporting.

The change in the size of the hotkey mask, the hability to report the keys
that use the higher bits, and the addition of the hotkey_radio_sw attribute
are important enough features to warrant increasing the minor field of the
sysfs interface version.
Also, document a bit better how and when the thinkpad-acpi sysfs interface
version will be updated.

Some ThinkPad models, notably the T60 and X60, have a slider switch to
enable and disable the radios. The switch has the capability of
force-disabling the radios in hardware on most models, and it is supposed
to affect all radios (WLAN, WWAN, BlueTooth).
Export the switch state as a sysfs attribute, on ThinkPads where it is
available.
Thanks to Henning Schild for asking for this feature, and for tracking down
the EC register that holds the radio switch state.

The firmware knows how many hot keys it supports, so export this
information in a sysfs attribute.
And the driver knows which keys are always handled by the firmware in all
known ThinkPad models too, so export this information as well in a sysfs
attribute. Unless you know which events need to be handled in a passive
way, do *not* enable hotkeys that are always handled by the firmware.

Revise ACPI HKEY functionality to better interface with the firmware, and
enable up to 32 regular hotkeys, instead of just 16 of them. Ouch.
This takes care of most keys one used to have to do CMOS NVRAM polling on,
and should drop the need for tpb, thinkpad-keys, and other such 5Hz NVRAM
polling power vampires on most modern ThinkPads ;-)
And, just to add insult to injury, this was sort of working since forever
through the procfs interface, but nobody noticed or tried an echo
0xffffffff > /proc/acpi/ibm/hotkey and told me it would generate weird
events. ARGH!
Thanks to Richard Hughes for kicking off the work that ended up with this
discovery, and to Matthew Garret for calling my attention to the fact that
newer ThinkPads were indeed generating ACPI GPEs when such hot keys were
pressed.

Add DMI-based aliases to allow module autoloading on select thinkpads.
The aliases will do nothing unless the dmi-based-module-autoloading.patch
patch from Lennart Poettering <mzxreary@0pointer.de> is applied. Lennart's
patch has been accepted by greghk and will be merged eventually.
