TouchWake implementation v1.4b (Yank555.lu)

- finger and pen working
- call detection working through proximity sensor detection
- use of wakelock is optional (sysfs switchable)
- fixed for CM11 ROMs
- reviewed digitizer handling

What's new :

- don't use proxy sensor state when suspending to decide whether or not to enable touchwake & small fixes

SysFs interface :

* /sys/class/misc/touchwake/enabled (rw) : 1 - on / 0 - off
*
* Enable / Disable TouchWake (default = disabled)
*
* NB: Turning the device off with the power key will disable touchwake
*
* /sys/class/misc/touchwake/delay (rw) :
*
* Sets the delay in ms to keep touchscreen / pen actively listening for touch after screen goes off
*
* NB: A value of 0 equals "infinite", will drain battery !
*
* /sys/class/misc/touchwake/proximity_threshold (rw) :
*
* Sets the threshold from which to consider the proximity sensor triggered (which will disable touchwake)
*
* NB: This serves as a kind of in-call detection to not turn the screen on during a call when placing
* the device to the ear
*
* /sys/class/misc/touchwake/use_wakelock (rw) : 1 - on / 0 - off
*
* Enable / Disable using a wakelock to keep device awake while TouchWake is active (default = enabled)
*
* /sys/class/misc/touchwake/version (ro) :
*
* Display the current version of TouchWake
*
* /sys/class/misc/touchwake/debug (ro) :
*
* Display debugging info (only if debugging is active at compilation time)

TouchWake implementation v1.4a (Yank555.lu)

- finger and pen working
- call detection working through proximity sensor detection
- use of wakelock is optional (sysfs switchable)
- fixed for CM11 ROMs
- reviewed digitizer handling

What's new :

- reduces proximity sensor detection default threshold
- added debug output to dmesg of proximity sensor reading

TouchWake implementation v1.4 (Yank555.lu)

- Finger and Pen working
- Call detection working through proxy detection
- use of wakelock is optional (sysfs switchable)
- fixed for CM11 ROMs
- reviewed digitizer handlingTouchWake implementation v1.3 (Yank555.lu)

- Finger and Pen working
- Call detection working through proxy detection
- use of wakelock is optional (sysfs switchable)
- fixed for CM11 ROMs

Issues left to resolve :

- Finger detection only works after screen is off for 1-2 seconds (though looks better on CM)

wacom: always disable digitizer when the pen is inserted

Inspired from CM11's, adapted Touchwake :

hlte: power enhancement for wacom hardware.

* always disable digitizer when the pen is inserted

TouchWake implementation v1.2 (Yank555.lu)

- Finger and Pen working
- Call detection working through proxy detection
- use of wakelock is optional (sysfs switchable)

Issues left to resolve :

- Finger detection only works after screen is off for 1-2 seconds

TouchWake implementation v1.1 (Yank555.lu)

- Finger and Pen working
- Call detection working through proxy detection

Issues left to resolve :

- Finger detection only works after screen is off for 1-2 seconds

TouchWake implementation v1.0 (Yank555.lu)

- Finger and Pen working

Issues :

- Finger detection only works after screen is off for 1-2 seconds
- Call detection missing to avoid turning the screen on when placing the device close to the ear
TouchWake implementation v1.5 (Yank555.lu)

- finger and pen working
- call detection working through proximity sensor detection
- use of wakelock is optional (sysfs switchable)
- fixed for CM11 ROMs
- reviewed digitizer handling

What's new :

- fixed TouchWiz KK kernel not keeping synaptics digitizer awake, finger touch now working

SysFs interface :

* /sys/class/misc/touchwake/enabled (rw) : 1 - on / 0 - off
*
* Enable / Disable TouchWake (default = disabled)
*
* NB: Turning the device off with the power key will disable touchwake

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend

Android early_suspend/late_resume PM kernel driver framework has been
deprecated by Google. This new powersuspend PM kernel driver is a replacement
for it and existing early_suspend drivers can be easily adapted to use this
new replacement driver
