[PATCH 5.13 019/175] arm64: dts: armada-3720-turris-mox: fixed indices for the SDHC controllers

From: Greg Kroah-Hartman
Date: Tue Aug 10 2021 - 13:53:41 EST


From: Vladimir Oltean <vladimir.oltean@xxxxxxx>

[ Upstream commit 923f98929182dfd04e9149be839160b63a3db145 ]

Since drivers/mmc/host/sdhci-xenon.c declares the PROBE_PREFER_ASYNCHRONOUS
probe type, it is not guaranteed whether /dev/mmcblk0 will belong to
sdhci0 or sdhci1. In turn, this will break booting by:

root=/dev/mmcblk0p1

Fix the issue by adding aliases so that the old MMC controller indices
are preserved.

Fixes: 7320915c8861 ("mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.14")
