Subject: [PATCH v3 00/18] arm64: allwinner: Add A64 DE2 HDMI support

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

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