Board:imx6q

linux kernel :3.0.35

I want to use it6251 conversion chip to convert LVDS signal into EDP signal. Now the conversion is successful, but there is a problem that the logo display interface is not displayed, and the app startup interface can be displayed normally，why?

I can't even try to initialize the chip by putting it into uboot。
