Android - Lolipop
Kernel - 3.10.53
I am working on Android Power Management. We have connected Keypad in POS board which is based on Android OS. After board goes to suspend mode if i press keypad or touch the touchscreen, board should not wake up(configured power Button as Wakeup source) . But now am getting issue like if I press keypad or touch the touchscreen, board is partially waking up (keypad light turns on and off suddenly) not waking up fully. What changes I need to do for stopping the partial wakeup ?
