c24b2602af spi: use simplified spi_sync() calling convention
Given the patch which simplifies the spi_sync calling convention, this one
updates the callers of that routine which tried using it according to the
previous specification.  (Most didn't.)

get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

e42837bcd3 freezer: introduce freezer-friendly waiting macros
Introduce freezer-friendly wrappers around wait_event_interruptible() and
wait_event_interruptible_timeout(), originally defined in <linux/wait.h>, to
be used in freezable kernel threads.  Make some of the freezable kernel
threads use them.

This is necessary for the freezer to stop sending signals to kernel threads,
which is implemented in the next patch.

7b6dff982b Input: usbtouchscreen - correctly set 'phys'
This patch fixes a nasty typo in usbtouchscreen driver. The typo
is inherited from the original mtouchusb. It used to make the input
subsytem to incorrectly report the physical device ids to userspace
that in turn is very confusing for, e.g. XInput hotplug facilities
in setups with multiple identical touchscreens.

1d25891f32 Input: ads7846 - re-check pendown status before reporting events
Pendown status from the PENIRQ pin is currently read only at the beginning
of a sample set. If the pen is lifted just after sampling has began then
sampled values become wrong.

This patch adds an optional platform penirq_recheck_delay attribute.  If
non-zero, samples are only reported to the input subsystem if PENIRQ is
still active that long after the samples taken.

e4f4886199 Input: ads7846 - introduce sample settling delay
The ads7846 driver has support for filtering, but when the chip gets
deselected between samples this causes noise. This patch adds support
for an optional settling delay time, so that two consecutive samples
will be taken with the specified delay time apart.  This ensures that
the chip won't be deselected, so the noise won't appear.

Filtering can still be done, but will have less work to do since each
time a new sample is taken the same delay applies.

8314418629 Freezer: make kernel threads nonfreezable by default
Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

230ffc8e34 Input: ads7846 - SPI_CPHA mode bugfix
In commit [1] the SPI mode is set to 1, but it should be 0.  As stated
in the commit, ads784x samples the data on the rising edge.  SPI mode 1
samples on the falling edge [2] though.

The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.

1936d590a9 Input: ads7846 - switch to using hrtimer
Use hrtimer instead of the normal timer, since it provides better
sampling resolution. This will:

 - avoid a problem where we have a 1 jiffy poll period and
   dynamic tick on
 - utilize high resolution HW clocks when they are added to
   the hrtimer framework

On some LCDs leaving the Vref on provides much better readings.

da970e69ef Input: ads7846 - pluggable filtering logic
Some LCDs like the LS041Y3 require a customized filtering
logic for reliable readings, so make the filtering function
replacable through platform specific hooks.

e1036502e5 [PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystem
Commit 2d4ba4a3b9 introduced a dependency
that was never meant to exist when the ac97_bus.c module was created.
Move ac97_bus.c up the directory hierarchy to make sure it is built when
selected even if sound is configured out so things work as originally
intended.

2d4ba4a3b9 [PATCH] ucb1400_ts depends SND_AC97_BUS
This driver is an AC97 codec according to its help text.  However, if SOUND is
disabled, the "select SND_AC97_BUS" still inserts that into the .config file:

#
# Sound
#
# CONFIG_SOUND is not set
CONFIG_SND_AC97_BUS=m

Even if the config software followed dependency chains on selects, we should
try to limit usage of "select" to library-type code that is needed (e.g., CRC
functions) instead of bus-type support.
