Including 'brcm,bt-pcm-int-params'? I don't see a BT reset signal
either, but maybe that's not pinned out in the AzureWave module which
was the only documentation details I could find[1].

I think a separate doc will be better as it can be more precise as to
what's allowed or not. It's fine to reuse the same property names
though.
