-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@...c0000 {
- compatible = "cdns,dsi";
- reg = <0x0 0xfd0c0000 0x0 0x1000>;
- clocks = <&pclk>, <&sysclk>;
- clock-names = "dsi_p_clk", "dsi_sys_clk";
- interrupts = <1>;
- phys = <&dphy0>;
- phy-names = "dphy";
- #address-cells = <1>;
- #size-cells = <0>;
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@1 {
- reg = <1>;
- dsi0_dpi_input: endpoint {
- remote-endpoint = <&xxx_dpi_output>;
- };
- };
- };

- compatible = "<vendor,panel>";
- reg = <0>;
