Subject: [PATCH] ARM: dts: exynos: Assign a fixed index to mmc devices on exynos4412 based ODROID boards
Date: Wed, 4 Nov 2020 11:25:56 +0100 [thread overview]
Message-ID: <20201104102558.11070-1-m.reichl@fivetechno.de> (raw)
Recently introduced async probe on mmc devices can shuffle block IDs.
Pin them to fixed values to ease booting in evironments where UUIDs ar not practical.
Use newly introduced aliases for mmcblk devices from [1].
