[PATCH 08/13] arm64: dts: ti: k3-j721e: Enable GPIO nodes at the board level
Andrew Davis

Wed Aug 2 13:53:04 PDT 2023
GPIO nodes defined in the top-level J721e SoC dtsi files are incomplete
and may not be functional unless they are extended with pinmux and
device information.
Disable the GPIO nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.
