2009-11-20Input: ucb1400_ts - allow passing IRQ through platfrom_dataMarek Vasut
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 <marek.vasut@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-08-21Input: ucb1400_ts - enable interrupt unconditionallyPavel Revak
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.

2009-08-21Input: ucb1400_ts - enable ADC FilterMarek Vasut
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.

2009-07-12Input: ucb1400_ts - fix a misleading function nameHans J. Koch
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.

2009-05-27Input: usb1400_ts - fix access to "device data" in resume functionManuel Traut
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 d9105c2b01 aka "[ARM] 5184/1: Split ucb1400_ts into core and touchscreen" Signed-off-by: Manuel Traut <manut@linutronix.de> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-04-17Input: ucb1400 - use disable_irq_nosync() in irq handlerBen Nizette
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 <bn@niasdigital.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-03-08Input: ucb1400_ts, mainstone-wm97xx - add BTN_TOUCH eventsMike Rapoport
Add BTN_TOUCH event reporting to ucb1400_ts and accelerated mainstone-wm97xx touchscreen drivers. Together with previously posted similar patch for wm97xx-core this will make all touchscreen drivers behave consistently wrt. BTN_TOUCH.

2008-08-20[ARM] 5184/1: Split ucb1400_ts into core and touchscreenMarek Vašut
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.

2008-04-24Input: ucb1400_ts - IRQ probe fixVernon Sauder
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.

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
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.

2007-10-18freezer: introduce freezer-friendly waiting macrosRafael J. Wysocki
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. Signed-off-by: Rafael J.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
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] Signed-off-by: Rafael J.

2007-04-10[PATCH] Input: ucb1400 - set up driver's name to show in sysfsCliff Brake
The UCB1400 is missing a name parameter in the device_driver struct. This causes missing information in the /sys tree and seems to cause other problems with the AC97 functionality.
