Wake DM8148 from GPIO or gpio_keys

David Paden

Hi,

I am testing out power management using the DM8148 EVM and a custom DM8148 board.  I have a key hooked to GPIO which is currently access through gpio_keys.  The key event is working well, but I need the system to wake from the key press.

What is needed to allow GPIO pins as a wake up source?  Serial console wake is good for debugging, but not most embedded applications.

Thanks,
