    Subject[PATCH 14/14] ARM: dts: sun8i: s3l: add support for Pine64 Single Cube Computer
    Date
    The Single Cube Computer kit by Pine64 is a development kit with
    Allwinner S3L SoC.

    It comes with a main board, an expansion board and a camera.

    The main board features a Micro-USB power-only jack, a USB Type-A port,
    an Ethernet port connected to the internal PHY of the SoC. A RGB LED
    port is reserved on the board.

    The expansion board features a TF slot, a microphone and a speaker
    connector with on-board amplifier.

    Add support for the kit, with features on the main board and the
    expansion board now.
