sunxi A33 MIPI DSI LCD support

[Mateusz Ferenc]

Hello,

I have a PC tablet based on Allwinner A33 CPU and have LCD connected to
MIPI DSI interface.
I searched a lot, including U-Boot sources, but unfortunately I didn't find
any way to use it with mainline U-Boot.
I extracted fex file from Android partition of this tablet and there are
data about DSI interface used, but I have no clue how to use it with
mainline.

If you could provide me any useful information how to make it work or if
there are no drivers for that CPU and it's interface so I could write
driver for it.

Any information will be appreciated.

Kind regards,
Mateusz Ferenc
