2011-02-23Input: omap4-keypad - wire up runtime PM handlingAbraham Arce1-19/+55
Enable Runtime PM functionality in OMAP4 driver based on the following assumptions: - keyboard controller in wakeup domain so it is always on and power impact is minimal; - in OMAP4 the device control is at module/device level and ick/fclk level control is difficult so cutting of clocks will prevent interrupts.

2011-02-23Input: serio/gameport - use 'long' system workqueueDmitry Torokhov2-2/+2
Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.

2011-02-02Revert "Input: do not pass injected events back to the originating handler"Dmitry Torokhov1-26/+11
This reverts commit 5fdbe44d033d059cc56c2803e6b4dbd8cb4e5e39. Apparently there exist userspace programs that expect to be able to "loop back" and distribute to readers events written into /dev/input/eventX and this change made for the benefit of SysRq handler broke them. Now that SysRq uses alternative method to suppress filtering of the events it re-injects we can safely revert this change.

2011-02-02Input: serio - clear pending rescans after sysfs driver rebindDuncan Laurie1-4/+7
When rebinding a serio driver via sysfs drvctl interface it is possible for an interrupt to trigger after the disconnect of the existing driver and before the binding of the new driver. This will cause the serio interrupt handler to queue a rescan event which will disconnect the new driver immediately after it is attached. This change removes pending rescans from the serio event queue after processing the drvctl request but before releasing the serio mutex. Reproduction involves issuing a rebind of device port from psmouse driver to serio_raw driver while generating input to trigger interrupts. Then checking to see if the corresponding i8042/serio4/driver is correctly attached to the serio_raw driver instead of psmouse.

2011-01-31Input: wacom_w8001 - report resolution to userlandPing Cheng1-2/+11
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.
