SW setting for wakeup from standby mode by ONOFF button

ko-hey — Tue, 20 Nov 2018 02:09:59 GMT

Hi all

I and my customer want to wake up from standby mode by ONOFF button.

I talked about it in following thread and guess I need something for make any unmasked interrupt by ONOFF behavior.

Do we have any SW setting for operating by ONOFF button ?

Unfortunately, our Linux version is very old (3.0.35), so if you are not have the same version you can use a different version of the reference.

Hi Ko-hey

please again check

" snvs power key driver. It work in imx chips after i.mx6sx ON/OFF key used power on/off whole system. This driver make it wakeup from suspend state when short press ON/OFF key."
