For testing only.

Version: V6

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 v5.1-rc1 the monitor doesn't blank on poweroff, it freezes
due to a patch revert some time ago.

  drm/rockchip: shutdown drm subsystem on shutdown
    https://patchwork.kernel.org/patch/10556151/
  drm/rockchip: Allow driver to be shutdown on reboot/kexec
    https://patchwork.kernel.org/patch/10556135/
  [for-4.20] Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"
    https://patchwork.kernel.org/patch/10714725/

DVI-D monitors without CEA modes can add a fixed mode
to the kernel command line as workaround.
For example: video=HDMI-A-1:1280x720@60

HDMI sound not included.
etc.
