* input: touchscreen: mxt224: Fix MT protocol implementation.Jeff Brown2011-11-171-14/+13
| | | | | | | | | | | | Correctly implement the MT protocol. Use ABS_MT_PRESSURE for intensity information. Use ABS_MT_TOUCH_MAJOR for touch width. Instead of sending ABS_MT_TOUCH_MAJOR with a value of 0 to indicate finger release, just omit the finger altogether. If there are no fingers left, then send an empty SYN_MT_REPORT / SYN_REPORT pair of events.

* Input: synaptics_i2c_rmi: Send new multi touch eventsArve Hjønnevåg2011-06-141-0/+25
| | | | | | | | | | | | Send both fingers using the new multitouch protocol in addition to the old single finger event and second finger ABS_HAT* hack. The new protocol does not specify how to report up events. To make sure the user-space frameworks can generate up events, we send at least one event where ABS_MT_TOUCH_MAJOR is zero before we stop sending events for a finger.

| | | | | | | | | | | | | | | | | | | | | | Depending on the quality of the touch panel, the time for the X-, X+, Y- and Y+ inputs to settle may vary. The poll_delay parameter can be used to override the default of 1 millisecond.

| * Input: tsc2007 - add max_rt parameter to platform dataThierry Reding2011-05-171-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finger touch events or very quick stylus events on low-quality panels can cause the tsc2007 to read bogus values. Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

Fix this by always disabling the pen down interrupt while data is active and vice versa. When a changeover is required we disable the IRQ that is to be stopped then schedule work that will enable the new IRQ. We need to handle the data flow in the data IRQ as the readback from the device needs to be ordered correctly with the IRQ for robust operation. This also fixes an issue when using the built in IRQs due to enable_irq() not being valid from interrupt context on an interrupt controller with bus operations like the built in IRQ controller - this issue may also have affected other interrupt controllers. We can't rely on having the data and pen down IRQs available via GPIOs on the CPU on every system.

| | * | | Input: tsc2005 - remove 'disable' sysfs attributeDmitry Torokhov2011-03-161-48/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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>
| | * | | Input: tsc2005 - don't use work for 'pen up' handlingDmitry Torokhov2011-03-161-31/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
