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)

 - toshiba,hpd-pin: TC358767 GPIO pin number to which HPD is connected to (0 or 1)

 - 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

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 {

			#address-cells = <1>;

			#size-cells = <0>;

			port@1 {

				reg = <1>;

				bridge_in: endpoint {

					remote-endpoint = <&dpi_out>;

				};

			};

			port@2 {

				reg = <2>;

				bridge_out: endpoint {

					remote-endpoint = <&panel_in>;

				};

			};

		};
