2011-03-13Input: wacom - support one finger touch the touchscreen wayPing Cheng2-90/+50
There are two types of 1FGT devices supported in wacom_wac.c. Changing them to follow the existing touchscreen format, i.e., only report BTN_TOUCH as a valid tool type. Touch data will be ignored if pen is in proximity. This requires a touch up event sent if touch was down when pen comes in. The touch up event should be sent before any pen events are emitted. Otherwise, two pointers would race for the cursor. However, we can not send a touch up inside wacom_tpc_pen since pen and touch are on different logical port. That is why we have to check if touch is up before sending pen events.

2011-02-27Input: evdev - fix evdev_write return value on partial writesPeter Korsgaard1-4/+6
As was recently brought up on the busybox list (http://lists.busybox.net/pipermail/busybox/2011-January/074565.html), evdev_write doesn't properly check the count argument, which will lead to a return value > count on partial writes if the remaining bytes are accessible - causing userspace confusion. Fix it by only handling each full input_event structure and return -EINVAL if less than 1 struct was written, similar to how it is done in evdev_read.

2011-02-25Input: atmel_mxt_ts - remove matrix size checkIiro Valkonen1-73/+0
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).

The MCS50XX series has a HW bug that requires explicit chip power down. If chip is not powered down before shutting the system down the control pins (powerup, interrupt) are pulled up and residue current continues flowing into the chips making them continue consuming power.

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.
