Allwinner A64 has display engine pipeline like other Allwinner SOC's A83T/H3/H5.
A64 DE2 behaviour similar to Allwinner A83T where mixer0, connected to tcon0 with
RGB, LVDS MIPI-DSI and mixer1, connected to tcon1 with HDMI.
This series merely concentrated on HDMI pipeline and rest will add eventually.
patch 1: dt-bindings for a64 DE2 CCU
patch 2: a64 DE2 CCU node addition
patch 3: dt-bindings for a64 DE2 pipeline
patch 4 - 5: dt-bindings for a64 mixer0 and tcon-lcd
patch 6: a64 DE2 pipeline node addition
patch 7 - 8: dt-bindings for a64 HDMI and HDMI PHY
patch 9: a64 HDMI nodes addition
patch 10 - 11: dt-bindings for a64 mixer1 and tcon-tv
patch 12: a64 HDMI pipeline
patch 13: enable HDMI out on bananpi-m64
Tested HDMI on bananapi-m64 (along with DE2 SRAM C changes from [1]
thread), able to detect the HDMI but, no penguins on screen.
Request for any suggestions.
Test log on Bananpi-m64:

DE2 in A64 has clock control unit and behavior is
same like H3/H5, so reuse the same in A64.

The display pipeline on A64 has similar behavior like A83T,
so use A83 compatible strings for probing relevant drivers.
Added Mixer0, tcon0 has initial support, rest will add eventually.

Unfortunately, that won't work in all cases. HDMI has two possible clock
parents and only one can be selected. If HDMI controller clock has PLL_VIDEO1
as a source, you will calculate wrong divider in HDMI PHY, since you will base
calculations on PLL_VIDEO0. I think driver needs an expansion.
That is also one of the reasons why I didn't yet send A64 HDMI patch series (I
didn't figure out this part yet). The other reason is that I'm waiting on SRAM
C claiming code.

Jernej

HDMI pipeline on A64 has similar behavior like A83T where
tcon1 is connected to HDMI. So reuse similar dts nodes for A64.

HDMI pipeline on A64 has similar behavior like A83T where
tcon1 is connected to HDMI. So reuse similar dts nodes for A64.

That doesn't seem to work so well for LVDS.

A good guess would be that you can't get the EDIDs for some
reason. Have you tried forcing a mode to see if the display part
already works?

Yes I've forced and used custom EDID with 1024x786 bin and observed
that the bin is able to load.
[ 0.262973] [drm] No driver support for vblank timestamp query.
[ 0.263842] [drm] Got built-in EDID base block and 0 extensions
from "edid/1024x768.bin" for connector

Yes I've forced and used custom EDID with 1024x786 bin and observed
that the bin is able to load.
[ 0.262973] [drm] No driver support for vblank timestamp query.
[ 0.263842] [drm] Got built-in EDID base block and 0 extensions
from "edid/1024x768.bin" for connector

This smells like HDMI voltage regulator not being enabled. You have to include
patch like this:
https://github.com/Icenowy/linux/commit/
27d12cd2fe89f64c5f4d5224984d4cbfcb7ee137
I guess it won't apply as-is, since it's based on my old, out-of-tree hdmi
driver.
Best regards,
Jernej

This smells like HDMI voltage regulator not being enabled. You have to include
patch like this:
https://github.com/Icenowy/linux/commit/
27d12cd2fe89f64c5f4d5224984d4cbfcb7ee137
I guess it won't apply as-is, since it's based on my old, out-of-tree hdmi
driver.

You are mising sunxi-ng clock patches. PLL_VIDEO0 and PLL_VIDEO1 need fixes by
setting minimum stable frequency. Please note that datasheet may have wrong
information. That was obvious in H3 case and I had to check minimum stable
PLL_VIDEO frequency in BSP driver.
Without clock fixes, you might not see anything on the screen.

Can you point me the clock patches? I've phadled only CLK_PLL_VIDEO0
on hdmi_phy So we need CLK_PLL_VIDEO1 as fourth clock?

Here is my A64 HDMI wip repo, which includes my clock changes:
https://github.com/jernejsk/linux-1/tree/a64_hdmi_wip
At some point HDMI output worked ok, I'm not sure in what state I left the
code.
> I've phadled only CLK_PLL_VIDEO0

I'm not sure what is the best way. I guess some research is needed. There is
even the possibility that one bit (SUN8I_HDMI_PHY_PLL_CFG1_CKIN_SEL) in hdmi
phy needs to be toggled depending on which clock is selected as HDMI source. I
never finished my research since I'm waiting to SRAM C claiming patches.
At the end, HDMI driver should be tested by both, PLL_VIDEO0 and PLL_VIDEO1 as
a HDMI clock source, otherwise there is no guarantee that we got binding
right. A83T, H3 and H5 has only one possible HDMI parent clock, so it was much
easier in this regard.
Unfortunately, BSP driver is not much of a help, since it was always
distributed as a blob. Disassembly looks much like H3 driver, with few bits
added. However, BSP clocks are pretty much hardcoded so they don't tell all
the story.
Best regards,
Jernej

Jernej, thanks for the regulator change in another mail, yes
bananapi-m64 has HVCC regulator for HDMI glue, with this I'm able to
see penguins on screen.

Actually, same diagram also shows that PLL_VIDEO0 can be connected to TCON1/
HDMI. Since DT descibes HW, probably both phandles should be specified and
driver should decide some way which one to select. Additionally, HDMI
controller and HDMI PHY should use same PLL at the same time. If nothing is
done, PLL_VIDEO0 will always be used, which might interfere in dual monitor
setup.
