From 013b7dd32c75ad3db218aa7a2d63f541304ac3b6 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Wed, 9 Aug 2023 19:38:03 -0500 Subject: [PATCH] arm64: dts: ti: k3-j7200: Enable SDHCI nodes at the board level SDHCI nodes defined in the top-level J7200 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.
