For testing only.

Version: V4

Title: Enable rk3066 VOP and HDMI for MK808.

This patch serie only works in combination with a MK808 TV stick and
a rk3066 processor. Other boxes and tablets with a rk3066
need extra software for power management and lcd's.

What does it do:

With these kernel patches a MK808 can show 2 penguins and a console
on a DVI-D monitor in combination with a framebuffer.

Not tested:

HDMI TV
HDCP
DRM
Xorg
Display managers
Android
etc.

Problems:

DRM functions keep changing every rc.
With v5.0-rc8 the monitor doesn't blank on poweroff, it freezes.
Fixed screen size for DVI-D.
HDMI sound not included.
etc.
