+Toshiba TC358767 eDP bridge bindings
+
+Required properties:
+ - compatible: "toshiba,tc358767"
+ - reg: i2c address of the bridge, 0x68 or 0x0f, depending on bootstrap pins
+ - clock-names: should be "ref"
+ - clocks: OF device-tree clock specification for refclk input. The reference
+ clock rate must be 13 MHz, 19.2 MHz, 26 MHz, or 38.4 MHz.
+
+Optional properties:
+ - shutdown-gpios: OF device-tree gpio specification for SD pin
+ (active high shutdown input)
+ - reset-gpios: OF device-tree gpio specification for RSTX pin
+ (active low system reset)
+ - ports: the ports node can contain video interface port nodes to connect
+ to a DPI/DSI source and to an eDP/DP sink according to [1][2]:
+ - port@0: DSI input port
+ - port@1: DPI input port
+ - port@2: eDP/DP output port
+
+[1]: Documentation/devicetree/bindings/graph.txt
+[2]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+ edp-bridge@68 {
+ compatible = "toshiba,tc358767";
+ reg = <0x68>;
+ shutdown-gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
+ reset-gpios = <&gpio3 24 GPIO_ACTIVE_LOW>;
+ clock-names = "ref";
+ clocks = <&edp_refclk>;
+
+ ports {
+ port@1 {
+ reg = <1>;
+
+ bridge_in: endpoint {
+ remote-endpoint = <&dpi_out>;
+ };
+ };
+
+ port@2 {
+ reg = <2>;
+
+ bridge_out: endpoint {
+ remote-endpoint = <&panel_in>;
+ };
+ };
+ };
+ };
