2010-02-26Input: atkbd - release previously reserved keycodes 248 - 254Dmitry Torokhov
Keycodes in 248 - 254 range were reserved for special needs (scrolling) of atkbd driver. Now that the driver has been switched to use unsigned short keycodes instead of unsigned char we can release this range back into pull. We keep code 255 (ATKBD_KEY_NULL) reserved since users may have been using it to silence keys they do not care about since atkbd silently drops scancodes mapped to this keycode.

2010-02-25Input: ads7846 - add regulator supportGrazvydas Ignotas
The ADS7846/TSC2046 touchscreen controllers can (and usually are) connected to various regulators for power, so add regulator support. Valid regulator will now be required, so boards without complete regulator setup should either disable regulator framework or enable CONFIG_REGULATOR_DUMMY.

2010-02-24Input: winbond-cir - fix suspend/resumeDavid Härdeman
This fixes suspend/resume problem with the driver caused by the fact that ACPI _DIS method would completely power off the SP3 module leaving the output lines (including IRQ lines) in an undefined state. This could cause spurious interrupts and requires reinitializing hardware from scratch during resume.

2010-02-20Input: polldev can cause crash in case when polling disabledSamu Onkalo
When polled input device is opened and closed and there are no other users of polled device, the workqueue is created and destroyed in every open / close operation. It is probable that at some point dynamic allocation of internal parts of the workqueue cause changes to the workqueue. When a work is queued to the workqueue the work struct contains pointers to the workqueue data. If the workqueue has been changed and the work has never been queued to the new workqueue, work-struct contains pointers to the non-existing workqueue. This will cause crash at the work cancellation during device close since cancellation of a work assumes that the workqueue exists. To prevent that, work struct is cleaned up at device close. This keeps work struct clean for the next use. Signed-off-by: Samu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Devices supporting both pen and touch features share the same product ID, but presented as 2 separate input devices.

Keys and switches are exported as stringified bitmap of codes (keycodes or switch codes). For example keys 15, 89, 100, 101, 102 are exported as: '15,89,100-102'.

2010-01-31Input: add imx-keypad driver to support the IMX Keypad PortAlberto Panizzo
The IMX family of Application Processors is shipped with a Keypad Port supported by this driver. The peripheral can control up to an 8x8 matrix key pad where all the scanning is done via software. The hardware provides two interrupts: one for key presses (KDI) and one for all key releases (KRI). There is also a simple circuit for glitch reduction (said for synchronization) made by two series of 3 D-latches clocked by the keypad-clock that stabilize the interrupts sources. KDI and KRI are fired only if the respective conditions are maintained for at last 4 keypad-clock cycle. Since those circuits are poor for a correct debounce process (the keypad-clock frequency is 32K and bounces longer than 94us are not masked) the driver, when an interrupt arrives, samples the matrix with a period of 10ms until the readins are stable for IMX_KEYPAD_SCANS_FOR_STABILITY times (currently set at 3). After getting stable result appropriate events are sent through the input stack. If some keys are maintained pressed, the driver continues to scan the matrix with a longer period (60ms) to catch possible multiple key presses without overloading the cpu. This process ends when all keys are released. This driver is tested to build in kernel or as a module and follow the specification of Freescale Application processors: i.MX25 i.MX27 i.MX31 i.MX35 i.MX51 especially tested on i.MX31.

2010-01-30Input: implement input filtersDmitry Torokhov
Sometimes it is desirable to suppress certain events from reaching input handlers and thus user space. One such example is Mac mouse button emulation code which catches certain key presses and converts them into button clicks as if they were emitted by a virtual mouse. The original key press events should be completely suppressed, otherwise user space will be confused, and while keyboard driver does it on its own evdev is blissfully unaware of this arrangement. This patch adds notion of 'filter' to the standard input handlers, which may flag event as filtered thus preventing it from reaching other input handlers. Filters don't (nor will they ever) have a notion of priority relative to each other, input core will run all of them first and any one of them may mark event as filtered. This patch is inspired by similar patch by Matthew Garret but the implementation and intended usage are quite different. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
