HP TouchPad key mappings for device buttons
This page is under construction and is served as a reference page for now
event0 covers multiple GPIO keys
event0 has 4 keys - KEY_VOLUMEDOWN, KEY_VOLUMEUP, KEY_REPLY and ?
event0 they names are self-explanatory except KEY_REPLY is the home key... the key labeled ? is literally labeled as ? and it's purpose is unknown
event1 is pmic8058_pwrkey with KEY_END and KEY_POWER
event2 is headset
tapping power sends KEY_END over event1, holding it (for 1/2 second) sends KEY_POWER
--event0 is on the CPU itself.
--event2 could be from the Audio Processor
