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

[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 {
#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>;
};
};
};
};
