I’m running Android 12 on SC200E development kit. I wanna wakeup board when tap the touch screen, now only PWRKEY can wakeup the board.

Dear, customer:
We usually use power key to suspend and wake up the system.
We never use touch screen to wake up the system.
If you need this featuer on your project, you can evaulate this feature first.
Thanks.

I know that PWRKEY can do the job, but I will not have PWRKEY at my final project. Could you give me directions of how can I exit from suspend using TP_INT pin?

Hi,
When the system enters sleep, TP driver is suspend, so we can’t wake up system from TP.
Have you already select your TP IC? I think TP driver should support this feature first.

Yes I use goodix GT928. It has a flag called slide-wakeup I have enable it in dtsi but doesn’t work. I was thinking that maybe I need to enable TP_INT as wake up source in some place first to get this feature of goodix work.

Maybe if you point me where PWRKEY is configured as wakeup source I can do simular with TP_INT.

I asked about development kit at beginning of this post because as it uses TP_INT too is more easy to get a answer for that than for a specific touch used at my project and process usually is similar.
