From 0f0677f6eb1797a007dadbad54538fde7102965c Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 4 May 2016 14:43:58 +0200 Subject: ARM: dts: exynos: Define vqmmc for SD card and allow disabling regulators on Odroid X/X2/U3 The SD-card vmmc-supply contained incorrectly two regulators. The second one is ignored. Fix this by defining proper vmmc and vqmmc supplies. Additionally these regulators do not have to be always on, so allow disabling them to reduce energy consumption.
