This patch allows UCB1400 to get IRQ GPIO from platform data. In case
platform_data are not supplied or the IRQ supplied in the platform_data
is negative, fall back to the old IRQ detection algorithm.Signed-off-by: Marek Vasut

Sometimes, when using the touchscreen, it stops working till next restart
and the following message is printed:ucb1400: unexpected IE_STATUS = 0x0
The following patch retriggers the touchscreen interrupt unconditionally.
This prevents hanging of the touchscreen in case of bogus interrupt
occurence.Signed-off-by: Pavel Revak

This patch enables ADC filtering on UCB1400 codec by default. The
benefit from this change is mostly on some Colibri boards where
the ADCSYNC pin of the UCB1400 codec isn't connected causing the
touchscreen to jitter very badly. This change has no visible
effect on boards where the ADCSYNC pin is connected.Signed-off-by: Marek Vasut

The driver for UCB1400 touchscreen controllers contains a function named
ucb1400_ts_pen_down(), but it returns 0 if the pen is down and 1 if it's up.
This causes confusion, especially since it's used as a boolean truth value
later in the code. This patch renames it.Signed-off-by: Hans J. Koch

platform_data != driver_data
driver data is actually the "correct" place of the struct however it is
not placed there due to the need of the ac97 struct. This is broken since

disable_irq() waits for all running handlers to complete before
returning. As such, if it's used to disable an interrupt from
that interrupt's handler it will deadlock. This replaces the
dangerous instances with the _nosync() variant which doesn't have
this problem.Signed-off-by: Ben Nizette

This patch splits ucb1400_ts into ucb1400_ts and ucb1400_core.
Since this chip supports more features than only touchscreen,
it was necessary to prepare it for feature addition. The
previous functionality is preserved by applying this patch.[Build fixes for non-ARM by Stephen Rothwell and Takashi Iwai]

The UCB1400 driver IRQ probe code fails to find an interrupt if all
the interrupts in the range 0-31 are nonprobe-able. This patch
removes the check of the return value so interrupts above 31 can be
detected.Tested on InHand Fingertip4 PXA270 board.

This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.Signed-off-by: Takashi Iwai

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.[akpm@linux-foundation.org: build fixes]
