My issus is gpio key can not wake up system sometimes !
Linux version 3.0.35 + imx6dq + two gpio keys.
Two gpio keys:key1,key2 with wakeup feature.
App read key1 input pressed event and then "stanby" system, press key2 wakeup system. but sometimes ,key2 can not wakeup system.
As can not wake up system by press key2, I wake up system by press key1. gpio key driver produce key1 and key2 interrupt. and I check gpc IRQ masking regs: mask bits is right.
