Some header files have moved so update #includes.
devs.h has been moved and updated. Delete the old version at
include/asm-arm/plat-s3c24xx as it is no longer used. Nothing to
migrate from this file to the new file at the new location.
s3c_device_i2c has become s3c_device_i2c0

This patch carries over the OpenMoko modifications at
include/asm-arm/arch-s3c2410/spi-gpio.h to
arch/arm/mach-s3c2410/include/mach/spi-gpio.h
Note: board_size and board_info have been removed upstream, but as we
still rely on them we'll just put them back for now. These will need to
be removed (and the corresponding driver changes made, of course) before
this can go upstream.

This pulls the Moko changes to regs-sdi.h that were in
include/asm-arm/arch-s3c2410 over to the file at arch/arm/../mach and
deletes the file at include/asm-arm.
Note: we have been using a mix of regs-sdi.h from the two different
locations. The unification of these two files may have some unknown
consequences... keep your eyes open for oddities after applying this.

This file already exists at arch/arm/mach-s3c2410/include/mach (where it
needs to be) and there are no OpenMoko changes to be carried over.

This "move" is not so much a file move as just carrying over the current
status of the irqs.h file from include/asm-arm/arch-s3c2410 to the file
at arch/arm/mach-s3c2410/include/mach. For some reason both files
existed and had become out of sync.
NOTE: Some of these changes look fishy... please check these properly.

This file was moved in the big file move, but some OpenMoko specific
changes did not make it. This patch peels out the relevant bits and
adds them to the gpio.h file in the upstream location.
The only OpenMoko specific change is the definition of gpio_to_irq and
irq_to_gpio. These functions should really be defined in gpio_chip and
asm-generic/gpio.h; this is coming soon, but until then we'll just use
the Moko definitions that we've been using up until now.
This is not strictly correct for the GTA02 case, but it works given
the configuration that's currently in use. This can be fixed (and
should become evident) when the configuration options are cleaned up.

This file is OpenMoko specific and didn't get moved in the big file
move. Move it to arch/arm/mach-s3c2410/include/mach where it belongs
and fix the references to it.

This patch adds the gta01 backlight callback that defers the
restoring of the backlight until after the jbt driver has
resumed. This doesn't eliminate the flashing of the LCD on
the gta01, but it reduces it considerably.

Touchscreen on GTA01-02 experiences noise on the channel that serves the
"tall axis" of the LCM. The sample quality of the other axis is good.
The bad samples have a characteristic of one shot excursions that can
reach +/- 20% or more of the sample average.
Previously, we had a simple averaging scheme going in the touchscreen
driver that summed up 32 x and ys and then divided it by 32. This patch
first tidies up the existing code for style, then adds a new "running
average" concept with a FIFO. The running average is separate from the
summing average mentioned above, and is accurate for the last n samples
sample-by-sample, where n is set by 1 << excursion_filter_len_bits in the
machine / platform stuff.
The heuristic the patch implements for the filtering is to accept all
samples, but tag the *previous* sample with a flag if it differed from
the running average by more than reject_threshold_vs_avg in either
axis. The next sample time, a beauty contest is held if the flag was
set to decide if we think the previous sample was a one-shot excursion
(detected by the new sample being closer to the average than to the
flagged previous sample), or if we believe we are moving (detected by
the new sample being closer to the flagged previous sample than the
average. In the case that we believe the previous sample was an
excursion, we simply overwrite it with the new data and adjust the
summing average to use the new data instead of the excursion data.
I only tested this by eyeballing the output of ts_print_raw, but it
seemed to be quite a bit better. Gross movement appeared to be
tracked fine too. If folks want to try different heuristics on top
of this patch, be my guest; either way feedback on what it looks like
with a graphical app would be good.

On GTA02 we use FIQ to manage the vibrator IO now. That
is necessary because we stole timer3 from doing hw pwm
for vibrator. This keeps the same UI in /sys but does
"bitbang pwm" on the same vibrator GPIO

Adds a C-based FIQ ISR which is very convenient (and unusual --
normally you have to do FIQ ISR in assembler only).
Based on my article:
http://warmcat.com/_wp/2007/09/17/at91rm9200-fiq-faq-and-simple-example-code-patch/
Implemented as a platform device and driver.
Suspend / resume is tested and works.

This is a MMC/SD driver for the Samsung S3C24xx SD/MMC controller, originally
developed years ago by Thomas Kleffel <tk@maintech.de>.
Due to time restraints, he had no time to further maintain the driver and
follow the mainline Linux changes in the SD/MMC stack.
With his authorization, I have taken over the task of making it compliant to
the current mainline SD/MMC API and take care of the mainline kernel merge.
After a potential kernel inclusion, we would co-maintain the driver.
