+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 VGA bridge input
+ Port 1 - output port representing the VGA 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>;
+ vga_bridge_input: endpoint {
+ remote-endpoint = <&xxx_dpi_output>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+ vga_bridge_output: endpoint {
+ remote-endpoint = <&xxx_vga_connector_input>;
+ };
+ };
+ };
+ };
