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 DiagramAllwinner_A64_User_Manual_V1.1.pdf

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

This series fixed previous version comments
- about documenting fallback compatibles
- adding new compatible for mixer1
- support for multiple DW HDMI PHY clock parents (thanks, to Jernej)

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.

There's no point in trying to push this without the SRAM issue being
solved. It is required, and won't be merged unless this is addressed.

is SRAM issue resolved? if so may be I will try to test it on top.

I'd expect the one working on this to push a solution to solve this.
