[PATCH 2/4] arm64: dts: ti: k3-am64-tqma64xxl-mbax4xxl: add muxing for GPIOs on pin headers

From: Matthias Schiffer
Date: Thu Sep 28 2023 - 07:45:44 EST


The pin headers X41 and X42 do not have a fixed function. All of these
pins can be assigned to PRG0, but as a default, it makes more sense to
configure them as simple GPIOs, as the MBaX4XxL is a starterkit/evaluation
mainboard.
