[PATCH v3 4/4] ARM: dts: add HS400 support for Exynos5420 and exynos5800

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Seungwon Jeon <tgih.jun@xxxxxxxxxxx>

HS400 timing value set is added for SMDK5420, peach-pit and
exynos5800 peach-pi.
And GPIO line for RCLK should be pull-down state.
