rtc: omap: add runtime pm support
OMAP1 RTC driver is used in multiple devices like, OMAPL138 and AM33XX.
Driver currently doesn't handle any clocks, which may be right for OMAP1
architecture but in case of AM33XX, the clock/module needs to be enabled
in order to access the registers.
So convert this driver to runtime pm, which internally handles rest.

rtc: omap: kicker mechanism support
OMAP RTC IP can have kicker feature. This prevents spurious writes to
register. To write to registers kicker lock has to be released.
Procedure to do it as follows,
1. write to kick0 register, 0x83e70b13
2. write to kick1 register, 0x95a4f1e0
Writing value other than 0x83e70b13 to kick0 enables write locking, more
details about kicker mechanism can be found in section 20.3.3.5.3 of
AM335X TRM @www.ti.com/am335x
Here id table information is added and is used to distinguish those that
require kicker handling and the ones that doesn't need it. There are more
features in the newer IP's compared to legacy ones other than kicker,
which driver currently doesn't handle, supporting additional features
would be easier with the addition of id table.
Older IP (of OMAP1) doesn't have revision register as per TRM, so revision
register can't be relied always to find features, hence id table is being
used.
While at it, replace __raw_writeb/__raw_readb with writeb/readb; this
driver is used on ARMv7 (AM335X SoC)

percpu_rw_semaphore: add lockdep annotations
Add lockdep annotations. Not only this can help to find the potential
problems, we do not want the false warnings if, say, the task takes two
different percpu_rw_semaphore's for reading. IOW, at least ->rw_sem
should not use a single class.
This patch exposes this internal lock to lockdep so that it represents the
whole percpu_rw_semaphore. This way we do not need to add another "fake"
->lockdep_map and lock_class_key. More importantly, this also makes the
output from lockdep much more understandable if it finds the problem.
In short, with this patch from lockdep pov percpu_down_read() and
percpu_up_read() acquire/release ->rw_sem for reading, this matches the
actual semantics. This abuses __up_read() but I hope this is fine and in
fact I'd like to have down_read_no_lockdep() as well,
percpu_down_read_recursive_readers() will need it.

percpu_rw_semaphore: kill ->writer_mutex, add ->write_ctr
percpu_rw_semaphore->writer_mutex was only added to simplify the initial
rewrite, the only thing it protects is clear_fast_ctr() which otherwise
could be called by multiple writers. ->rw_sem is enough to serialize the
writers.
Kill this mutex and add "atomic_t write_ctr" instead. The writers
increment/decrement this counter, the readers check it is zero instead of
mutex_is_locked().
Move atomic_add(clear_fast_ctr(), slow_read_ctr) under down_write() to
avoid the race with other writers. This is a bit sub-optimal, only the
first writer needs this and we do not need to exclude the readers at this
stage. But this is simple, we do not want another internal lock until we
add more features.
And this speeds up the write-contended case. Before this patch the racing
writers sleep in synchronize_sched_expedited() sequentially, with this
patch multiple synchronize_sched_expedited's can "overlap" with each
other. Note: we can do more optimizations, this is only the first step.

percpu_rw_semaphore: reimplement to not block the readers unnecessarily
Currently the writer does msleep() plus synchronize_sched() 3 times to
acquire/release the semaphore, and during this time the readers are
blocked completely. Even if the "write" section was not actually started
or if it was already finished.
With this patch down_write/up_write does synchronize_sched() twice and
down_read/up_read are still possible during this time, just they use the
slow path.
percpu_down_write() first forces the readers to use rw_semaphore and
increment the "slow" counter to take the lock for reading, then it
takes that rw_semaphore for writing and blocks the readers.
Also. With this patch the code relies on the documented behaviour of
synchronize_sched(), it doesn't try to pair synchronize_sched() with
barrier.

Akita machines have backlight controls hooked to a gpio expander chip,
max7310 using i2c transfers which can sleep. In this case,
pca953x_gpio_set_value() can be called to control gpio, and
pca953x_setup_gpio() sets can_sleep flag. Therefore,
gpio_set_value_cansleep() should be used in order to avoid WARN_ON on
akita machines.
Akita is the only exception in this case since other users of corgi_lcd
access backlight gpio controls through a different gpio expander which
does not set the can_sleep flag.

drivers/video/backlight/lp855x_bl.c: use generic PWM functions
The LP855x family devices support the PWM input for the backlight control.
Period of the PWM is configurable in the platform side. Platform
specific functions are unnecessary anymore because generic PWM functions
are used inside the driver.
(PWM input mode)
To set the brightness, new lp855x_pwm_ctrl() is used.
If a PWM device is not allocated, devm_pwm_get() is called.
The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'.
To get the brightness value, no additional handling is required.
Just the value of 'props.brightness' is returned.
If the PWM driver is not ready while initializing the LP855x driver, it's
OK. The PWM device can be retrieved later, when the brightness value is
changed.
Documentation is updated with an example.

.gitignore: remove stale entry for generated version.h
Since userspace headers were moved to generated/uapi it possible to have a
stale copy of linux/version.h at that file's old location. This causes
confusion after building an older kernel version, then checking out and
building a new one; the old (stale) version header will still get picked
up until it is manually removed. This upsets the C library.
Since the uapi changes, include/linux/version.h is no longer generated and
