I think you already got that comment but audio2 is a terrible name.
Given that the 2nd controller is mostly about VAD (PDM is there only to
feed it) and that it is just a name, I'd prefer something like a1_audio_vad.

Why do you have to do that and cannot do it like the rest of the

It does not make a lot of sense that one of the 2 controllers as 2nd
pclk.
You should consider using the AUD2_CLKID_AUDIOTOP as a parent of audio
gates instead. You would not have to that.

Again this is over-complicated.
Just make an external function for the register, use it for axg, a1,
a1-vad, then make one file for each controller. That will keep the code
clean and readable.
keep it simple please.
