[PATCH v1 1/2] dt-bindings: drm/bridge: anx7625: MIPI to DP transmitter binding

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:
anx_bridge: anx7625@58 {
compatible = "analogix,anx7625";
reg = <0x58>;
low-power-mode = <1>;
dsi-supported = <1>;
dsi-channel-id = <1>;
dsi-lanes-num = <4>;
internal-pannel-supported = <1>;
pon-gpios = <&gpio0 45 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpio0 73 GPIO_ACTIVE_LOW>;
status = "okay";
port {
anx7625_1_in: endpoint {
remote-endpoint = <&mipi_dsi_bridge_1>;
};
};
};
