88d27041cf ARM: S3C6410: Correct names of IISv4 data output pin definitions

e9c08f0d57 ARM: S3C64XX: Redo voltage ranges for cpufreq
The documentation for the S3C6410 CPU voltage scaling is rather
unclear, with omitted values for several speed settings. Originally
the code was using only quoted values, resulting in some fairly odd
settings. The S3C6410 is also unusual in that the both the maximum
and minimum voltages quoted scale as the frequency rises, rather
than just the minimum voltage.

Clean this up a bit by always using the specified typical settings
as the minimum voltage (ignoring any specified minimum voltage) in
order to avoid running near the edge of the processor capabilities.
Also use the next quoted maximum voltages rather than the typical
voltages where no maximum voltage is quoted, allowing operation on
a greater range of systems.

43f1069ef9 ARM: S3C64XX: Separate out regulator and frequency latencies
Currently the transition latency reported by the S3C64xx cpufreq
driver includes both the time for the CPU to reclock itself and
the time for a regulator to change voltage. This means that if
a regulator is not in use then the transition latency reported
is excessively high.

In future the regulator API will be extended to report latencies
so the driver will be able to query the performance of a given
regulator.

42015c133b ARM: SMDK6410: Hook up regulator supplies for WM8580
DVDD is supplied by supplies derived from the PMIC, AVDD and PVDD are
supplied from the main wall supply on the base board which runs at
5V. No option is currently supported for running without a PMIC card,
the assumption is that the regulator API will be built out when no
soft PMIC card is in use.

To ease merge issues since this uses the newly added dev_name supply
configuration from the regulator API (currently in -next only) the
fixed voltage regulator is ifdefed out when the regulator API is not
enabled.

276b282e90 pps: events reporting fix up
PPS events must be recorded according to PPS's mode settings.

If a process asks for (i.e.) capture-assert events only, when the PPS
client calls the pps_event() function to save the current PPS event, we
should verify the event type and then discard unwanted ones.

Also, without this patch userland processes waiting for a specific PPS
event (assert or clear but not both) may be awakened at wrong time.

Userland programs may read/write PPS parameters at same time and these
operations may corrupt PPS data.

69fd8d2467 drivers/video/msm: update to new kernel
TASK_INTERRUPTIBLE and friends are now only available after including
<linux/sched.h>, so include it when needed.

bus_id is no longer available/necessary, so remove that.

Android pmem driver is not available in mainline, so remove its hooks
from drivers/video.

d62668e1dd gpiolib: fix device_create() result check
In case of failure, device_create() returns not NULL but the error code.
The current code checks for non-NULL though which causes kernel oops in
sysfs_create_group() when device_create() fails.  Check for error using
IS_ERR() and propagate the error value using PTR_ERR() instead of fixed
-ENODEV code returned now...

bcb3a1676b rtc: v3020: fix v3020_mmio_read_bit()
v3020_mmio_read_bit() always returns 0 when left_shift > 7.

v3020_mmio_read_bit()'s return type is (unsigned char).  The code returns
a value masked by (1 << left_shift) that is casted to the return type.  If
left_shift is larger than 7, the cast will always result in a 0 return
value.  The problem was discovered with left_shift = 16, and the included
patch corrects the problem.

The bug was introduced in the last (Apr 3 2009) commit of the file, kernel
versions 2.6.30 and later.
