Allwinner A64 has display engine pipeline like other Allwinner
SOC's A83T/H3/H5.

A64 behaviour similar to Allwinner A83T where
Mixer0 => TCON0 => LVDS/RGB/MIPI-DSI
Mixer1 => TCON1 => HDMI
as per Display System Block Diagram from
Allwinner_A64_User_Manual_V1.1.pdf

This is third patch-set followed with previous RFC[1], first and
second
series[2][3] and merely concentrated on HDMI pipeline through
TCON1 and
rest will add eventually.

This series fixed previous version comments
- Rebasing on linux-next
- sqash all pipeline components in one patch
- Enable all pipeline components in board dts
- about documenting fallback compatibles
- adding new compatible for mixer1

You still haven't figured out the SRAM parts. We asked you to fix
this
in the v1 and the v2 already, and we're not going to merge this
without those bits figured out properly.

Sorry I'm not sure what I'm trying to do on SRAM here because the
last
mail, I have waited for Icenowy changes about simple_fb with sram_c
on
ccu node and those are merged. can you elaborate please.

Would you mind me advance the patchset a bit and send a PATCH v3.1?

I won't finally take the maintainership of the patchset.

Note:
Pine64 boards are unable to get edid by default like other A64
boards,
but forcing 'video=HDMI-A-1:1920x1080@60D' kernel command line
can
create edid with display on penel

Then that needs to be figured out before it's enabled, instead of
having a hack that barely works.

Any suggestion to work.
