From 51ed312aa5072c920f86c308565232e98e4d9079 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Tue, 15 Nov 2022 16:27:27 +0100 Subject: arm64: dts: qcom: sm6375-pdx225: Configure Samsung touchscreen Add a pretty bog-standard-for-Xperias-for-the-past-3-years touchscreen setup. The OEM that built the Xperia 10 IV for SONY decided to use some kind of a GPIO regulator that needs to be enabled at all times for both the touch panel and the display panel to function.
