From a427d15062ac46a00a22d2f0b9d05093c18ff2f1 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 7 Nov 2014 08:22:49 +0900 Subject: [PATCH] ARM: dts: Add micro SD card SDHCI node for exynos4412-trats Add SDHCI node for supporting the micro SD card. On Trats2 board the SDHCI does not use sd2_cd pins (gpk2-2) for card detect but gpx3-4 instead. Power is supplied from LDO21 regulator which in off state is controlled by external GPIO pin.
