[PATCH v9 1/2] dt-bindings: drm/bridge: anx7625: MIPI to DP transmitter binding

From: Xin Ji
Date: Thu Apr 30 2020 - 05:34:24 EST


The ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed
for portable device. It converts MIPI to DisplayPort 1.3 4K.

You can add support to your board with binding.

Example:
anx7625_bridge: encoder@58 {
compatible = "analogix,anx7625";
reg = <0x58>;
status = "okay";
enable-gpios = <&pio 45 GPIO_ACTIVE_HIGH>;
reset-gpios = <&pio 73 GPIO_ACTIVE_HIGH>;
#address-cells = <1>;
#size-cells = <0>;

ports {
#address-cells = <1>;
#size-cells = <0>;

mipi2dp_bridge_in: port@0 {
reg = <0>;
anx7625_in: endpoint {
remote-endpoint = <&mipi_dsi>;
};
};

mipi2dp_bridge_out: port@1 {
reg = <1>;
anx7625_out: endpoint {
remote-endpoint = <&panel_in>;
};
};
};
};
