Yes, thanks, I figured it out from driver. One more thing that I've not already
searched - the DP lanes init, actually we need 2 lanes for FHD 24-bit mode as
mentioned in DP brochures (they mention it in comparison table with LVDS
interface). I may be wrong at this point, just a suggestion. But flickering,
that I saw is about quarter of screen on left top corner.
