IMX8MN + SN65DSI83: cannot connect bridge

AyrtonL — Wed, 18 Jun 2025 13:06:20 GMT

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:

Hi Aldo

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