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.
