IMX8M mini MIPI_DSI DRM device not loading

HI ,

We have custom IMX8M board with ILI9881C panel.

I have Modified kconfig and compiled with ili988c Driver

I have also Enabled ili device node in DTS

&mipi_dsi {
status = "okay";
panel1: panel@0 {
reg = <1>;
compatible = "bananapi,lhr050h41","ilitek,ili9881c";
reset-gpios = <&gpio3 12 1>;
power-supply = <&reg_mipi_phy>;
backlight = <&backlight>;
};

};

I don't see any kind of error while booting on drm/mipi/ or ili,

When i checked the code I could see that the device attach is not working properly saying that the drm_mipi bus has no device .

The device driver is unchanged . Only change I did was to enable it in dts.
