[PATCH v2 0/8] Initial Allwinner Display Engine 2.0 Support

[Icenowy Zheng]

This patchset is the initial patchset for Allwinner DE2 support.

It contains the support of clocks in DE2 and the mixers in DE2.

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, although its clock control
unit contains support for second mixer's clock; 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!
