    Subject[PATCH v4 9/9] arm64: allwinner: h6: add support for Pine H64 board
    Date
    Pine H64 is an Allwinner H6-based SBC from Pine64, with the following
    features:

    - 1GiB/2GiB/4GiB LPDDR3 DRAM (in 4GiB situation only 3GiB is
    accessible)
    - AXP805 PMIC
    - Raspberry-Pi-compatible GPIO header, "Euler" GPIO header (not
    compatible with the "Euler" on Pine A64) and "Expansion" pin header
    - 2 USB 2.0 ports and 1 USB 3.0 ports
    - Audio jack
    - MicroSD slot and eMMC module slot
    - on-board SPI NOR flash
    - 1Gbps Ethernet port (via RTL8211E PHY)
    - HDMI port

    Adds initial support for it, including the UART on the Expansion pin
    header.
