FIrst of all, did you run make dt_binding_check?
I wonder there're dt binding missing for a few nodes

this depends on pinctrl driver. Is that upstreamed already?

this could be added when enabling DSP in case any changes required in upstream

I belive this is still not supported in upstream
so drop it first

i'd suggest drop it first and add in separate patch
as it's still not supported
