[PATCH 3/5] arm64: dts: qcom: sdm845-xiaomi-beryllium-common: add touchscreen related nodes

From: Joel Selvaraj
Date: Sun Mar 12 2023 - 05:33:25 EST


Enable qupv3_id_1 and gpi_dma1 as they are required for configuring
touchscreen. Also add pinctrl configurations needed for touchscreen.
These are common for both the tianma and ebbg touchscreen variant.
In the subsequent patch, we will initially enable support for the focaltech
touchscreen used in the EBBG variant. This is done in preparation for that.
