From 0e63f35a9c6acf1d74bd693c492f8955bb16c89a Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Thu, 20 Oct 2022 11:03:00 -0500 Subject: arm64: dts: ti: k3-j721s2: Enable UART nodes at the board level UART nodes defined in the top-level J721s2 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.
