2011-03-24Input: tsc2005 - fix locking issueAaro Koskinen
Commit 0b950d3 (Input: tsc2005 - add open/close) introduced a locking issue with the ESD watchdog: __tsc2005_disable() is calling cancel_delayed_work_sync() with mutex held, and the work also needs the same mutex. Fix the problem by using mutex_trylock() in tsc2005_esd_work(). If the mutex is taken, we know we are in the middle of disable or enable and the watchdog check can be skipped.

2011-03-17Input: tsc2005 - remove 'disable' sysfs attributeDmitry Torokhov
I believe that enable/disable functionality should not be implemented on the individual driver level but rather in device core, potentially reusing parts of PM framework. Therefore the driver-specific "disable" attribute is removed from the mainline driver. Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-03-17Input: tsc2005 - add open/closeDmitry Torokhov
Introduce open and close methods for the input device to keep the device powered down when it is not in use. Also rework interaction between interrupt thread and starting/shutting off/resetting the device: instead of taking a mutex in the intterrupt thread and elsewhere disable interrupts before transitioning the device in a new state. The ESD handling is also separated from the IRQ thread; we poll regularly at a given interval and simply skip reads if we see that valid interrupt happened not so long ago. This allows us not cancel and reschedule ESD work from interrupt context all the time. Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

We will most likely rearm it yet again the IRQ thread so doing it here is pointless. Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-03-17Input: tsc2005 - don't use work for 'pen up' handlingDmitry Torokhov
We do not need process context to send input events so let's switch to a regular timer. I am going to get rid of taking ts->mutex in tsc2005_irq_thread() later. Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-03-17Input: tsc2005 - do not use 0 in place of NULLDmitry Torokhov
Sparse in unhappy when people use 0 instead of NULL for pointers so let's rework the way we initialize spi_transfer structure in tsc2005_cmd() and tsc2005_write(). Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-03-17Input: tsc2005 - rework driver initialization codeDmitry Torokhov

2011-02-25Input: atmel_mxt_ts - remove matrix size checkIiro Valkonen
The mxt_check_matrix_size() is currently setting the CTE mode to match xline/yline information that is in the platform data, but it does not take into account for example the fact that we could have a key array in use too (key array would use some x/y lines as well). It would be better to simply rely on the configuration data, and make sure that the CTE mode set in there matches the touch object (touchscreen, key array, proximity) configuration (which are set in the config data too).

2011-02-01Input: wacom_w8001 - report resolution to userlandPing Cheng
Serial devices send both pen and touch data through the same logical port. Since we scaled touch to pen maximum, we use pen resolution for touch as well here. This is under the assumption that pen and touch share the same physical surface. In the case when a small physical dimensional difference occurs between pen and touch, we assume the tolerance for touch point precision is higher than pen and the difference is within touch point tolerance. A per-MT tool based resolution mechanism should be introduced if the above assumption does not hold true for the pen and touch devices any more.

Platform data is supported to allow configuration of system parameters such as selection between four and five wire touchscreens and for specification of optional direct to CPU IRQs for sample availability and for pen down.
