[PATCH] arm64: dts: rockchip: add SD/eMMC aliases for ArmSom Sige5
Posted by Sebastian Reichel 2 weeks, 6 days ago
Provide aliases for the SD and eMMC interfaces, so that the operating
system can assign stable interface names.

On Linux this is only relevant when booting without partition UUID
based root device identification, e.g. when booting without an
initramfs. In that case booting with e.g. root=/dev/mmcblk0p2 is
unreliable without this patch as the device numbers changed based
on device probe order.
