Part Number: SN65DSI84

Tool/software:

Hi,

We are using imx8mq custom som in that add support for 7 inch LVDS Linux 6.1.22 BSP.

MIPI DSI TO DUAL LINK LVDS BRIDGE = SN65DSI84 IC.

Driver file path below mentioned.

github.com/.../ti-sn65dsi83.c

While booting the board observed below error prints.

" [drm:drm_bridge_attach] *ERROR* failed to attach bridge /soc@0/bus@30800000/mipi-dsi@30a00000 to encoder None-34: -517" 

Kindly tell your solution to fix the issue above issue.

	dsi_lvds_bridge: sn65dsi84@2c {
		compatible = "ti,sn65dsi84";
		reg = <0x2c>;
		vcc-supply = <&reg_1p8v>;
		enable-gpios = <&gpio3 0 GPIO_ACTIVE_HIGH>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_lvds_bridge>;
		status = "okay";
	
		 ports {
                        #address-cells = <1>;
                        #size-cells = <0>;

		port@0 {
		        reg = <0>;
			bridge_in: endpoint {
				remote-endpoint = <&dsi_out>;
				data-lanes = <1 2 3 4>;
				};
			};
			
		port@2 {
		        reg = <2>;
			bridge_out: endpoint {
				remote-endpoint = <&panel_in_lvds>;
			 };
		 };
	 };
   };
