Hi,

These add support for DSI on V4H SoC (r8a779g0) and DP for Whitehawk
board.

The last patch is a hack, but needed to get the DSI working. It is still
unclear what the register write does, and as that patch is needed to get
the DSI working, this series is not ready yet. But all the rest of the
patches are ready for review.

And I forgot to mention, these are based on:
