I was asking for the code to be generic, not the binding itself. If the
code could for example take a property name as an argument that'd allow
other bindings to use the same code without having to have a generic
binding which has bits which depend strongly on some Linux specific

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.
