[PATCH v8 0/9] Initial Allwinner Display Engine 2.0 Support

[Icenowy Zheng]

This patchset is the initial patchset for Allwinner DE2 support.

As the DE2 CCU support is already applied, this patchset now contains
only DRM changes and device tree changes. 

The SoC used to develop this patchset is V3s, as V3s is the simplest
one of the SoCs that have DE2.

(Allwinner V3s features only one mixer, and its only video output is
RGB LCD, which is already supported in our TCON driver)

The last patch is only a testing patch, it shouldn't be merged; and
for the patch to be really usable, the RFC fix of the TCON driver [1]
is needed.

No HDMI, TV encoder or other internal bridges' support is included
in this patchset, which makes it currently not usable on H3.

Thanks to Jean-Francois Moine and Jernej Skrabec for their efforts
to discover the internal of DE2!
