[PATCH v2 00/29] Allwinner H6 DE3 and HDMI support

[Jernej Skrabec]

This series adds support for Display Engine 3.0 and HDMI 2.0a, which
can be found on H6 SoC.

Display Engine 3.0 in comparison to 2.0 mostly adds features needed for
displaying and processing 10-bit and AFBC formats, which are not yet
supported by this series.

This series is based on linux-next at next-20180828, which has working
R40 display pipeline support. I'll rebase series on later linux-next, if
needed, once R40 display pipeline support is reintroduced.

I suggest all patches go through allwinner tree, except DRM patches,
which should go through drm-misc tree.

Last detail, PineH64 model A schematic has DDC_EN signal, which enables
DDC voltage level shifter. TL Lim, PINE64 founder, said that this
signal is not actually present on PineH64 model A board. It is, however
present on PineH64 model B engineering samples, but it will be removed
in production version. Because of that, I didn't include any code for
it.

Please take a look.

Best regards,
Jernej

Changes from v1:
- Collected tags
- Reworked some commit messages and titles

- Fixed kbuild test robot warnings
- renamed CLK_NUMBER to CLK_NUMBER_WITHOUT_ROT and introduced
  CLK_NUMBER_WITH_ROT
- removed "inline" from functions in c file
- used regmap_bulk_write() for writing DE3 CSC table
