uboot splash fades when transitioning to kernel, mipi dsi

I am working with i.MX8MP with mipi display where I want to pass uboot splash through linux kernel, till application will take over.

I have figured that when imx8mp_clocks_probe in clk-imx8mp.c is called (specificaly of_clk_add_hw_provider()) the splash from uboot starts fading and a few black lines at random place are showing. When it comes to application everything works ok.

When I show the linux kernel logo the corrupt/fading uboot splash is replaced with kernel logo successfully.

Have you got any idea what to do?

Hello,

I guess this is due to bad a initialization, you better configure the clock all right or make sure that is not sharing the same with another port.
