I'm no expert on this and I'm just asking in case you have missed one of these: Can you confirm that these belong to some other IP? Best regards, Martin

I just found an old comment from Rob on v2 of this series: [0] He mentions: "If this is a child of something else, then put a $ref to this schema and the example in the parent schema." To be honest: I completely forgot about that comment until now. If I had remembered it (and assuming that his comment is still valid) then I would have had to NACK my own Documentation/devicetree/bindings/phy/amlogic,meson8-hdmi-tx-phy.yaml For today it's already late so I'll look into this more tomorrow.

The Amlogic G12A SoCs embeds an Analog MIPI D-PHY to communicate with DSI panels, this adds the bindings. This Analog D-PHY works with a separate Digital MIPI D-PHY.
