This patch provides initial support for CPU frequency scaling on the
Samsung S3C64XX series processors. Currently only S3C6410 processors
are supported, though addition of another data table with supported
clock rates should be sufficient to enable support for further CPUs.

Add support for reconfiguring the clock for the ARM core, enabling
CPUfreq support. Currently only the divider for ARMCLK may be changed,
ARMPLL is left static.

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.

for 3d7k.
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.

Note: this patch is already on the way upstream but is currently missing
in the Openmoko kernel.
Some of the rate selection logic in s3c64xx_setrate_clksrc uses what
appears to be parent clock selection logic. This patch corrects it.
I also added a check for overly large dividers to prevent them
from changing unrelated clocks.
