[PATCH 1/3] ARM: dts: msm8974-FP2: Add support for touchscreen

From: Luca Weiss
Date: Thu Apr 21 2022 - 17:43:59 EST


Configure the touchscreen found on the new display module of the FP2.
To add some detail, FP2 has two different screen/touchscreen variants
("display module"), the old module has Synaptics touchscreen, the new
one this Ilitek touchscreen.

We're only supporting the new display module for now.
