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
+The ANX7625 is an ultra-low power 4K Mobile HD Transmitter +designed for portable devices.
+Required properties:
- compatible : "analogix,anx7625"
- reg : I2C address of the device
- anx,low_power_mode : Low power mode support feature
- anx,dsi_supported : DSI or DPI
- anx,dsi_channel : DSI channel index
- anx,dsi_lanes : DSI lane count
- anx,intr-hpd-gpio : Which GPIO to use for interrupt
+Optional properties:
- anx,extcon_supported
- external connector interface support flag
- anx,internal_pannel
- Which indicate internal pannel
- anx,p-on-gpio
- Which GPIO to use for Power On chip
- anx,reset-gpio
- Which GPIO to use for RESET
- port
- SoC specific port nodes with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt,
