From 132f80803e7ab85f11db5c6a7f5c464504e66a99 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 7 Apr 2025 22:01:50 +0200 Subject: [PATCH] arch: arm: dts: an7581: Add eMMC nodes Add eMMC nodes with the fixed regulator and fixed clock. It's also needed to assign the clock and set it to 200MHz as it's set to 150Mhz by default.
