[PATCH v2 6/7] arm64: dts: qcom: sc8280xp-crd: use external pull up for touch reset

From: Johan Hovold
Date: Tue May 07 2024 - 10:49:42 EST


The touch controller reset line is currently not described by the
devicetree except in the pin configuration which is used to deassert
reset.

As the reset line has an external pull up to an always-on rail there is
no need to drive the pin high so just leave it configured as an input
and disable the internal pull down.
