From 885fdf7b13beb72eacc964345becc0adf811c46c Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 4 May 2016 14:44:00 +0200 Subject: [PATCH] ARM: dts: exynos: Lower SD card interface voltage to 2.8 V 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 and 2.8 V is common on Exynos-based boards. Additionally use some descriptive name for this regulator.
