    Subject[PATCH v2 02/13] arm64: dts: rockchip: Add Hardkernel ODROID-M1 board
    Date
    From: Dongjin Kim <tobetter@gmail.com>

    This patch is to add a device tree for new board Hardkernel ODROID-M1
    based on Rockchip RK3568, includes basic peripherals -
    uart/eMMC/uSD/i2c and on-board ethernet.
