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
