Hi Andrey

based on documentation from below link seems android 9 is not supported for i.MX6Q

i.MX Software | NXP 

General approach for adding support for new lcd is to change "display-timings" as in example on

i.MX6Q LVDS Wrong clock issue 

NXP BSP supports for i.MX6Q Sabre SD LCD described on
