From 006d93519db2e0eacbaeac20cf9d55a4d842a006 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Fri, 17 Nov 2023 10:33:38 -0600 Subject: arm64: dts: ti: k3-am65: Enable SDHCI nodes at the board level SDHCI nodes defined in the top-level AM65 SoC dtsi files are incomplete and will not be functional unless they are extended. As the attached SD/eMMC is only known about at the board integration level, these nodes should only be enabled when provided with this information. Disable the SDHCI nodes in the dtsi files and only enable the ones that are actually pinned out on a given board.
