From 9965228c662b25abfe3c16cbef82640074d79839 Mon Sep 17 00:00:00 2001 From: Boris Mittelberg Date: Thu, 25 Mar 2021 22:38:22 +0000 Subject: [PATCH] mainboard/google/brya: Disable touchpad as S3 wake source This change disables touchpad interrupt, as it sends spurious wake signal via GPP_F14 and immediately wakes the system from S3. It happens because touchpad's power is gated by deassertion of PLTRST#. The behaviour for S0ix is unchanged.
