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@60D' kernel command line can create edid with display on penel
