[U-Boot] [PATCH v3 0/6] sunxi: video: Add support for HDMI output on A64/H3/H5

[Jernej Skrabec]

This series implements support for HDMI output. This is done using
DM video framework and sharing the HDMI controller code with RK3288.

Patch 1 splits out TCON code which is completely reusable on
all Allwinner SoCs.

Patch 2 converts common TCON code to use DM video compatible timing
structure.

Patch 3 adds all necessary clocks which are needed for Display
Engine 2, TCON and HDMI.

Patch 4 implement actual DE2 and HDMI driver and patch 5 disables HDMI
on all boards which don't have it (default is on).

Patch 6 is included here only for testing HDMI output on A64 due
to missing power regulator support (AXP803). Another option is to
use ATF which powers on HDMI. Such ATF can be found on Andre
Przywara's github.

Code was tested on OrangePi 2 & OrangePi Plus 2E (both H3),
OrangePi PC 2 (H5) and Pine64 (A64). It was tested on A10, A13 and A20
boards by others.

This series was developed on u-boot-sunxi repository with additional,
not yet merged, patch: https://patchwork.ozlabs.org/patch/735617/

All Rockchip patches were already merged to u-boot-rockchip repository
and are not yet present in u-boot-sunxi. They have to be cherry picked:

Changes in v3:
- drop patch 1 because it was merged
- changed video output to 32 bpp
- collect acked by tags
- convert preprocessor symbol to Kconfig option (patch 3)
- Kconfig option in patch 4 depends on new option

Changes in v2:
- patch 1 & 2 were removed because they were merged
- collect reviewed by and tested by tags
- TCON split out patch is splitted in two patches
- fixed lcdc_enable() calls in video driver for old SoCs
- defconfigs should disable video driver, not enable it
- minor constant style fix
