    Subject[PATCH v4 17/22] ARM: dts: exynos: Add initial support for Odroid XU board
    Date
    The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
    from Samsung: the Exynos5410. Comparing the board to more popular now
    Odroid XU3, the differences are:
    1. Exynos5410 instead of 5422,
    2. MIPI DSI LCD connector,
    3. Main PMIC: Maxim 77802 instead of S2MPS11,
    4. USB3503+LAN9730 instead of integrated LAN9514,
    5. eMMC 4.5 instead of eMMC 5.0,

    This patch adds initial support for the XU board with working basic
    functions, eMMC/SD and USB (including attached ethernet adapter).
