This series adds support for R40 HDMI pipeline. It is a bit special than other already supported pipelines because it has additional unit called TCON TOP responsible for relationship configuration between mixers, TCONs and HDMI. Additionally, it has additional gates for DSI and TV TCONs, TV encoder clock settings and pin muxing between LCD and TV encoders.
However, it seems that TCON TOP will become a norm, since newer Allwinner SoCs like H6 also have this unit.
I tested different possible configurations: - mixer0 <> TCON-TV0 <> HDMI - mixer0 <> TCON-TV1 <> HDMI - mixer1 <> TCON-TV0 <> HDMI - mixer1 <> TCON-TV1 <> HDMI
Please review.
Best regards, Jernej
