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 RK3288 HDMI code in a way that it is appropriate
for sharing with Allwinner SoCs.
Patch 2 splits out TCON code which is completely reusable on
all Allwinner SoCs.
Patch 3 (new) converts commont TCON code to use DM video compatible
timing structure.
Patch 4 adds all necessary clocks which are needed for Display
Engine 2, TCON and HDMI.
Patch 5 implement actual DE2 and HDMI driver and patch 6 disables HDMI
on all boards which don't have it (default is on).
Patch 7 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 also tested on RK3288 Tinker
board. However, it was only compile tested for A10 and A20 targets.
This series was developed on u-boot-sunxi repository with additional,
not yet merged, patch: https://patchwork.ozlabs.org/patch/735617/
Because already merged patches are not yet included in u-boot-sunxi
repository, they need to be cherry picked from u-boot-rockchip:

520c174b3564ae183f0e7c118dc8ce3770ae20b0
Best regards,
Jernej Skrabec
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

Designware HDMI controller and phy are used in other SoCs as well. Split
out platform independent code.
DW HDMI has 8 bit registers but they can be represented as 32 bit
registers as well. Add support to select access mode.
EDID reading code use reading by blocks which is not supported by other
SoCs in general. Make it more general using byte by byte approach, which
is also used in Linux driver.
Finally, not all DW HDMI controllers are accompanied with DW HDMI phy.
Support custom phys by making controller code independent from phy code.

TCON unit has similar layout and functionality also on newer SoCs. This
commit splits out TCON code for easier reuse later.

Changes in v2:
- lcdc conversion to use struct display_timing is done in a new patch
- fix issue with lcdc_enable() calls

To: u-boot
Video driver for older Allwinner SoCs uses cfb console framework which
in turn uses struct ctfb_res_modes to hold timing informations. However,
DM video framework uses different structure - struct display_timing.
It makes more sense to convert lcdc to use new timing structure because
all new drivers should use DM video framework and older drivers might be
rewritten to use new framework too.

To: u-boot
Because DE2 driver is enabled by default, it is nice to disable it on
all boards which don't have any video output. List of such boards is
also much shorter.

Changes in v2:
- invert logic (disable instead of enable)

I tested the patched U-Boot on A10 with HDMI and A13 with LCD, and
it works properly.

This should be a Kconfig option.
Looks good otherwise, thanks!

So hidden option in board/sunxi/Kconfig will probably be the best then?
VIDEO_DE2 option added in patch 5 should depend on that symbol then.

Yes, I guess, but I'm not entirely sure why you need two different
options there?

I used define for CONFIG_SUNXI_DE2 here because SoC has or has not DE2 IP block
and that is not a choice. Option in patch 5 is configurable and gives
opportunity to build video driver or skip it, whithout influencing clock
structure.
I could make only one option, but then it would have to be configurable, which
doesn't really make sense from patch 4 perspective, because, as I already
stated before, this is property of the SoC.
Which solution do you prefer? One option, define and option (as it is now) or
two options?
Frankly, none of them is ideal. Best solution would be to convert clocks to
use driver model framework.

Jernej

I guess you could make a hidden Kconfig option selected by the
relevant MACH_ options.
As a general basis, we move away from the old-style config options, so
adding any new !Kconfig options isn't really an option.

doesn't work well with 16 BPP.

Not at all, I think it's also what we use in the previous SoCs.
