This patch moves items of the s3c24xx support into
a new plat-s3c directory for items that use the
s3c24xx support but are not directly s3c24xx
compatible, such as the s3c2400 and s3c6400.

In order for this driver to be shared across the iop architectures the
iop3xx and iop13xx header files are modified to present a common interface
for the iop_wdt driver.
Details:
* iop13xx supports disabling the timer while iop3xx does not. This requires
a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to
preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code.
* The heartbeat interval is derived from the internal bus clock rate, so this
this patch also exports the tick rate to the iop_wdt driver.

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.

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.
