Subject[PATCH v2] ARM: dts: exynos4412-trats: Add micro SD card SDHCI node
Date
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.

Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>

Changes since v1:
1. Drop FIXME comment (about findings during testing).
