From 7bfb6a4289b0a63d67ec7d4ce3018cb4a7442f6a Mon Sep 17 00:00:00 2001 From: Johan Hovold johan+linaro@kernel.org Date: Tue, 7 May 2024 16:48:19 +0200 Subject: [PATCH] arm64: dts: qcom: sc8280xp-x13s: fix touchscreen power on
The Elan eKTH5015M touch controller on the X13s requires a 300 ms delay before sending commands after having deasserted reset during power on.
Switch to the Elan specific binding so that the OS can determine the required power-on sequence and make sure that the controller is always detected during boot.
Note that the always-on 1.8 V supply (s10b) is not used by the controller directly and should not be described.
