It looks like there is no binding document at all for cdn-dp? At least
I couldn't find one and the original series also didn't seem to include one.

And while I don't see anything problematic right with the used properties
right now, I'd think we should really have a binding and give dt-maintainers
a chance to complain, before adding devicetree nodes based on it.

I'd guess a mostly usable binding doc should already sit in the chromeos
tree, which you could base a v2 of this series on?


Thanks
Heiko

Sure, I'll send a v2 for this series. Thanks.

So seems that the binding was already discussed and accepted here [1]
but for some reason never landed. So I think that I'll send v2 just
including the binding patch so all can land together. Sounds good?

Nice find and yep, just resending binding + your patches 2+3
is enough then :-)
