IMX8MN + SN65DSI83: cannot connect bridge

Hi

 

I am unable to get the MXSFB working.
The driver failed with:

platform 32e00000.lcdif: deferred probe pending: mxsfb: Cannot connect bridge

After having a few EPROBE_DEFER..

It looks like it is not finding a panel or a bridge.
I am using the MIPI_DSI as output to a TI - SN65DSI83.
Any help is appreciated.

I am using the imx8mn.dtsi devictree include and kernel 6.9.0

I added below part to my devicetree.

&i2c1 {
	status = "okay";
	
	dsi_lvds_bridge: sn65dsi83@2d {
		compatible = "ti,sn65dsi83";
		reg = <0x2d>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_panel>;
		enable-panel-gpios = <&gpio5 3 GPIO_ACTIVE_HIGH>;
		backlight = <&backlight>;
		status = "okay";

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

			port@0 {
				reg = <0>;

				ti_mipi_in: endpoint {
					remote-endpoint = <&host_mipi_out>;
					data-lanes = <1 2 3 4>;
				};
			};

			port@2 {
				reg = <2>;

				ti_mipi_out: endpoint {
					remote-endpoint = <&dsim_from_lcdif>;
				};
			};
		};
	};
};

&lcdif {
	status = "okay";
};

&mipi_dsi {
	status = "okay";
	
	port@1 {
		host_mipi_out: endpoint {
			remote-endpoint = <&ti_mipi_in>;
			attach-bridge;
		};
	};
	
};

&gpu {
	status = "okay";
};

Hello,

Could you share the kernel version that you are working with?
Also, please have a look to the following thread:

Best regards/Saludos,

Hi Aldo

I am using 6.9.0 upstreamed (so not the NXP ones)
