Subject: [PATCH v4 01/29] dt-bindings: display: rockchip,inno-hdmi: Document RK3128 compatible
The integration for this SoC is different from the currently existing: It
needs it's PHY's reference clock rate to calculate the DDC bus frequency
correctly. The controller is also part of a powerdomain, so this gets added
as an mandatory property for this variant.

changes in v2:
- clarify that the controller itself is part of the powerdomain
- simplify clock-names
- made power-domains property only allowed (and required) for new variant
changes in v3:
- collect RB
changes in v4:
- none
