Thanks for the pointer, has this series been merged?
Dont see it in topic/core in Mark's tree.

I will take a look but fwiw this statement is not entirely true in the cover
letter of patch:

"This will allow any component to have DAPM widgets and routes, which was
previously only possible for CODECs, and will allow any component to have DAPM
widgets with controls (i.e. Mixers and MUXs), which was previously only possible
for CODECs"

I am already running a system which models platform and has Mixers,
Muxes and works fine (tested on 3.10 and 3.14).

Few bits of code is in RFC I sent earlier and will post these in detail over
next few weeks
