I'm having issues enabling mipi-dsi on my custom board with imx8mm processor. My panel is connected and only thing working is backlight when connected.
I'm not really sure I configured my mipi-dsi correctly because I'm getting error 22 while trying to probe.
dmesg | grep dsi
[ 0.271214] platform 32c00000.bus:mipi_dsi@32e10000: Fixing up cyclic dependency with 32c00000.bus:lcdif@32e00000

I enabled st7701 in kernel, and all DSI stuff.
short version of DTS file:
&gpu {
status = "okay";
};
&lcdif {
status = "okay";
};
&mipi_dsi {
status = "okay";
panel@0 {
compatible = "techstar,ts8550b", "sitronix,st7701";
reg = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_mipi_dsi_rst>;
reset-gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>;
VCC-supply = <&ldo2_reg>;
IOVCC-supply = <&ldo2_reg>;
backlight = <&gpio1 1 GPIO_ACTIVE_LOW>;
};
pinctrl_mipi_dsi_rst: pinctrl_mipi_dsi_rst { fsl,pins = <
MX8MM_IOMUXC_GPIO1_IO11_GPIO1_IO11 0x16
>;
};
Any suggestions? I saw people using raydium67191 but I'm not really sure how...
