-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
-

-		reg = <0x68>;
-		shutdown-gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
