Identifiers related to the "camera" clock were mis-named as camif.
This patch renames them.

This dirty hack adds camera activation/deactivation on open/close.
This code will have to move to a machine/platform area later. The
general driver is the wrong place for it.
It also removes the unconditional activation and moves the domain
setting to the rest of the power control code. (Thanks, Andy !)
Note that opening the camera now always takes about 20 seconds
until the settings are downloaded, not just on the first open.

Filter chains should be completely opaque to the drivers that use it.
We fix this with this patch.
~ Make the "filter chain" a new object.
~ We can build with CONFIG_TOUCHSCREEN_FILTER=n with no problems in
a cleaner way.
~ Update s3c2410_ts.c to use the filter_chain object.
~ Cleanups.

~ Make a few symbols constant.

This patch defines a ts_filter_configuration structure to
avoid using void* in the filter initialization, fixing another
upstream correction. This also makes the initialization more readable.
Tested in GTA02/rev6.
Other changes:
~ Comment filter configuration structures.
~ ts_filter.c:ts_filter_chain_create improved.
~ Small cleanups.
~ More TODOs/FIXMEs.
~ Updated GTA02 filter configuration.
~ Updated GTA01 filter configuration.
~ Updated mach-s3c2410/include/mach/ts.h for the new ts. configuration
structure.
~ Updated all the filters to use the new configuration structure.
~ Removed MAX_TS_FILTER_CHAIN constant that is no longer needed.
No more evil casts left it seems.

This patch turns upstream feedback into API modifications and code
improvements. There will be more patches implementing upstream
corrections but this one is the that will make most of the invasive
changes and make the most important improvements to the API.
Tested in a GTA02/rev06.
The goals of this patch are:
* Replace recursive calls with iteration.
* General code improvements.
* Make ts_filter_mean.c a reference for the rest of the filters.
* Make the (almost)minimum number of changes to the other filters so
that they compile and work, patches for cleaning these up will
come next.
* Filters should do what they were doing before.
Some important changes:
* Move "struct ts_filter tsf" in the private structures to force
a crash (or break things) if we forget to remove an open-coded cast.
* ts_filter.c/ts_filter.h
~ API modifications.
* s3c2410_ts.c:
~ Use the new API.
~ Cleanups.
* ts_filter_mean.c
~ Replace with a simple mean.
~ Use as a reference for the new API.
~ Move private structure from the .h to the .c.
* ts_filter_group.c
~ Update to use the new API.
* ts_filter_median.c
~ Update to use the new API.
* ts_filter_linear.c
~ Remove functions that are no longer needed.
Note:
I might leave some TODOs and FIXMEs with this patch. Most of them
will be removed shortly.

The PLL converts a 26.6 MHz input clock to 87.8 MHz, which is later
divided by two and becomes PCLK. (See comments below for details.)
All this looks like a textbook example for platform stuff, but let's
take it one step a time.

The current version of CPU detection patch from Mark Brown and
Kyungmin Park takes a dump on system_rev. This patch changes it
to retain the low 16 of system_rev from the bootloader ATAG, and
adds access #defines and changes to use them.
No doubt they'll issue a better version of the CPU detection
patch and then this can be reverted.

Use the regulator framework to provide optional support for DVFS in
the S3C64XX cpufreq driver. When a software controllable regulator
is configured the driver will use it to lower the supply voltage when
running at a lower frequency, giving improved power saving.
When regulator support is disabled or no regulator can be obtained
for VDDARM the driver will fall back to scaling only the frequency.

Change accelerometers to use ABS events rather than REL events.
[Obviously if this patch is accepted we need to tell developers about
it. I have a number of other improvements to the accelerometers I
hope to deliver over the next couple of weeks. They will have minimal
or zero disruption to current code. ]
REL events should be used when there is no absolute reference, and
only changes are meaningful. The classic example is a "mouse" where
the absolute position of the device is not measurable and not
particularly meaning, but change in position from one time to the next
is interesting.
With REL events, a value of '0' is not reported, as 'not change' is
not interesting.
With REL events, the expectation is that successive values will be
eventually summed (possibly with acceleration and clipping
adjustments) to get a usable value.
ABS events should be used when there is an absolute references against
which things that be measured.
With ABS events, the 'current value' is meaningful and can be read
(EVIOCGABS).
With ABS events, the value '0' is very meaningful and is reported.
However if consecutive values are the same, the value is only reported
once.
ABS events can be used as-is or compared with previous events to get
some measure of change.
An obvious example is a touchscreen where each measure in
independently meaningful.
Acceleration is an absolute value as it is measuring against a frame
of reference. '0' acceleration is just as meaningful as any other
value, and finding the 'current' acceleration is each direction is a
potentially useful thing to do.
The Freerunner accelerometers currently report REL events. This is
wrong. So this patch changes them to report ABS events.
With this patch, the min/max/level/fuzz values are left at zero. It
might be useful to make use of these in a subsequent patch.
min/max/level can be used to calibrate the accelerometers if accuracy
is important.
fuzz could possibly be used in conjunction with the 'threshold' sysfs
value to get less frequent, lower-precision reports.
This may well break some applications that read accelerometer data.
This cannot be helped, but it is quite easy to write code that copes
with the incorrect EV_REL events as well as the more correct and
useful EV_ABS events.

The camera driver reduced all IO drivers from their reset defaults of
6 mA to only 2 mA, which caused severe signal distortion at higher
speeds. This patch sets them to 8 mA and also removes apparently
useless repetitions of the setting.
Note that the correct setting of the I2C pullups still needs to be
verified.

By parsing kernel command, 3d7k can probe two different LCM driver accordingly.
The default attached LCM device is l1k002, if you wanna to use jbt6k74, you don't
need to re-compile the kernel. Just add one option om_3d7k_lcm=jbt6k74 in
boot/append-OM_3D7K in rootfs.

A few dirty hacks to make the camera driver work:
- because V4L no longer guarantees that minor numbers provided by the
client are actually used, the preview/codec selection mechanism falls
apart. We work around this by defaulting to preview when we don't
know better.
- power up the camera in platform code, not cleanly via power control
device.
