The Multi Innotechnology is a 10.1" 1280x800 panel.
The datasheet did not specify specific values for sync, back, front porch. The values are a best guess based on values for similar panels.

Here you specify DISPLAY_FLAGS_DE_HIGH.

And here DRM_BUS_FLAG_DE_HIGH. I see that some other panels do this too and some only specify one of them. Do you know if they are redundant or one of them is ignored?
