    arm64: dts: cn913x: add device trees for COM Express boards · c11e7732

    Add support for CN9130 and CN9131 COM Express Type 7 CPU
    module boards by Marvell.
    Define these COM Express CPU modules as dtsi and
    provide a dtsi file for a carrier board (Marvell AC5X RD
    COM Express type 7 carrier board).
    This Carrier board only utilizes the PCIe link, hence no
    special device / driver support is provided by this dtsi file.
    Finally, provide a dts file for the com express carrier and
    CPU module combination.
    
    These COM Express boards differ from the existing CN913x DB
    boards by the type of ethernet connection (RGMII),
    the type of voltage regulators (not i2c expander based)
    and the USB phy (not UTMI based).
    Note - PHY + RGMII connector is OOB on CPU module.
    CN9131 COM Express board is basically CN9130 COM Express board
    with an additional CP115 I/O co-processor, which in this case
    provides an additional USB host controller on the board.
