-Cadence DSI bridge
-==================
-
-The Cadence DSI bridge is a DPI to DSI bridge supporting up to 4 DSI lanes.
-
-Required properties:
-- compatible: should be set to "cdns,dsi".
-- reg: physical base address and length of the controller's registers.
-- interrupts: interrupt line connected to the DSI bridge.
-- clocks: DSI bridge clocks.
-- clock-names: must contain "dsi_p_clk" and "dsi_sys_clk".
-- phys: phandle link to the MIPI D-PHY controller.
-- phy-names: must contain "dphy".
-- #address-cells: must be set to 1.
-- #size-cells: must be set to 0.
-
-Optional properties:
-- resets: DSI reset lines.
-- reset-names: can contain "dsi_p_rst".
-
-Required subnodes:
-- ports: Ports as described in Documentation/devicetree/bindings/graph.txt.
-  2 ports are available:
-  * port 0: this port is only needed if some of your DSI devices are
-           controlled through  an external bus like I2C or SPI. Can have at
-           most 4 endpoints. The endpoint number is directly encoding the
-           DSI virtual channel used by this device.
-  * port 1: represents the DPI input.
-  Other ports will be added later to support the new kind of inputs.
-
-- one subnode per DSI device connected on the DSI bus. Each DSI device should
-  contain a reg property encoding its virtual channel.
-
-Example:
-       dsi0: dsi@fd0c0000 {
-               compatible = "cdns,dsi";
-               reg = <0x0 0xfd0c0000 0x0 0x1000>;

-               interrupts = <1>;
-               phys = <&dphy0>;
-               phy-names = "dphy";
-               #address-cells = <1>;
-               #size-cells = <0>;
-
-               ports {
-                       #address-cells = <1>;
