    +Cadence MHDP bridge
    +==========================
    +
    +The Cadence MHDP bridge is a DPI to DP bridge.
    +
    +Required properties:
    +- compatible: should be "cdns,mhdp8546",
    +- reg: physical base address and length of the controller's registers,
    +- clocks: DP bridge clock, it's used by the IP to know how to translate
    + a number of clock cycles into a time (which is used to comply
    + with DP standard timings and delays),
    +
    +Required subnodes:
    +- ports: Ports as described in Documentation/devictree/bindings/graph.txt
    + Port 0 - input port representing the DP bridge input
    + Port 1 - output port representing the DP bridge output
    +
    +Example:
    +
    + mhdp: dp-bridge@f0fb000000 {
    + compatible = "cdns,mhdp8546";
    + reg = <0xf0 0xfb000000 0x0 0x1000000>;
    + clocks = <&mhdp_clock>;
    +
    + ports {
    + #address-cells = <1>;
    + #size-cells = <0>;
    +
    + port@0 {
    + reg = <0>;
    + dp_bridge_input: endpoint {
    + remote-endpoint = <&xxx_dpi_output>;
    + };
    + };
    +
    + port@1 {
    + reg = <1>;
    + dp_bridge_output: endpoint {
    + remote-endpoint = <&xxx_dp_connector_input>;
    + };
    + };
    + };
    + };
