It's starting to get an idiomatic way of representing the external
nodes, HDA is probably a good source of inspiration :)  We do need to
have a think about the jacks, though - simple ones are fine but
multifinction is more fun.

I just wanted to confirm that you're talking about multiple audio
functions here (e.g. mic+headphones), rather than mixing audio with
other features (e.g. s-video + line out). I don't think the latter has

Both.

any kind of representation in the kernel right now though? That said,

Depends; if you listen to Lennart and Kay it's totally there already and
there's nothing to worry about.

it might be a good idea to represent jacks outside any audio complex
DT node, so that they could host functionality of different types if
the HW does so...

Clearly, and even audio jacks have non-audio functionality like buttons.
