-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
-
-[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>;
