Subject[PATCH v2 00/27] Add support for R40 HDMI pipeline
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,

Changes from v1:
- Split DT bindings patch and updated description
- Split HDMI PHY patch
- Move header file from TCON TOP patch to dt bindings patch
- Added Rob reviewed-by tag
- Used clk_hw_register_gate() instead of custom gate registration code
- Reworked TCON TOP to be part of of-graph. Because of that, a lot of
new patches were added.
- Droped mixer index quirk patch
- Reworked TCON support for TCON TOP
- Updated commit messages
