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 as per Display System Block DiagramAllwinner_A64_User_Manual_V1.1.pdf
This is the first series on Allwinner A64 DE2 HDMI support which followed with previous RFC series [1] (thanks to Maxime, Jernej for comments on RFC series) and rest will add in future patches.
patch 1: dt-bindings for a64 de2 ccu
patch 2: add node support for a64 de2 ccu
patch 3: enable DE2_CCU for Allwinner 64-bit SoCs
patch 4: dt-bindings for a64 de2 pipeline
patch 5: add support for a64 de2
patch 6: defconfig: enable CONFIG_DRM_SUN4I
patch 7 -8: dt-bindings for a64 HDMI and HDMI PHY
patch 9: add support for a64 HDMI
patch 10: enable DesignWare HDMI for Allwinner 64-bit SoCs
patch 11 - 12: dt-bindings for a64 mixer1 and tcon1
patch 13: enable de2 mixer for Allwinner 64-bit SoCs
patch 14: add support for a64 HDMI pipeline
patch 15: add support for HVCC regulator
patch 16: enable HDMI out for bananapi-m64
patch 17: enable HDMI out for nanopi-a64
patch 18: enable HDMI out for orangepi-win
patch 19: enable HDMI out for a64-olinuxino
patch 20: enable HDMI out for pine64
patch 21: enable HDMI out for sopine
Since this series added HDMI through mixer1 through tcon1, I have used CLK_PLL_VIDEO1 as pll-0 we need to update the driver to support both CLK_PLL_VIDEO0 and 1 once we have add hdmi through mixer0.
Note: with pine64 and sopine, I'm unable to see any display on screen but loadded fine, request to verify anyone.
