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>; anx,low_power_mode = <1>; anx,dsi_supported = <1>; anx,dsi_channel = <1>; anx,dsi_lanes = <4>; anx,internal_pannel = <1>; anx,p-on-gpio = <&gpio0 45 GPIO_ACTIVE_LOW>; anx,reset-gpio = <&gpio0 73 GPIO_ACTIVE_LOW>; status = "okay"; port { anx7625_1_in: endpoint { remote-endpoint = <&mipi_dsi_bridge_1>; }; }; };

OK, I'll follow the yaml format in the next version. Thanks, Xin
