Thanks for the series, it's a really good cleanup.

I know that dw-hdmi-qp can support _any_ infoframe, by manually
packing it into the two GHDMI banks. So the supported set there is
'all of the currently well-known ones, plus any two others, but only
two and not more'. I wonder if that has any effect on the interface
you were thinking about for userspace?

Cheers,
Daniel
