[PATCH RFC 0/3] Input - Tap to wake for FT5452
From: David Heidelberg via B4 Relay
Date: Wed Nov 04 2026 - 07:59:18 EST
Sending RFC just to validate if this would be the correct approach to
implementing the tap toi wake functionality
I've tested this patch, it does wake up the phone.
The second assessment is let device shell to react to double-tap input
device when phone is only in screen-off mode, thus the second input
device to bind to (when touchscreen is in the runtime sleep).
Feel free to skip detailed review for RFC v1, I'll polish the code for
upcoming v2 submission, after design discussion and approval.
Thanks
