From 65e8781ac90e74242ebb1a98bf415809e8387aaf Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Fri, 28 Oct 2022 09:24:07 -0500 Subject: arm64: dts: ti: k3-am65: Enable UART nodes at the board level UART nodes defined in the top-level AM65x SoC dtsi files are incomplete and may not be functional unless they are extended with pinmux information. As the pinmux is only known at the board integration level, these nodes should only be enabled when provided with this information. Disable the UART nodes in the dtsi files and only enable the ones that are actually pinned out on a given board.
