Subject: [PATCH v2 3/3] ARM: dts: exynos: Lower SD card interface voltage to
2.8v on Odroid X/X2/U3
Odroid X/X2/U3 schematics say that SD card vmmc regulator
(LDO21/TFLASH) operates on 2.8 V. Mainline U-Boot uses that value as
well. 2.8 V is common on Exynos-based boards. Additionally use some
descriptive name for this regulator.
