[PATCH] ARM: dts: exynos: Assign a fixed index to mmc devices on ODROID XU3/4 boards

From: Markus Reichl
Date: Wed Nov 04 2020 - 05:51:44 EST


Recently introduced async probe on mmc devices can shuffle block IDs.
Pin them to fixed values to ease booting in evironments where UUIDs
are not practical. Use newly introduced aliases for mmcblk devices from [1].
