Nothing here explains why EXISTING hardware is being changed. I also
remember big discussions and big confusing patches regarding sa8775p
(its rename, dropping/changing all providers), and this patch feels like
pieces of it without proper justification.

And this is hidden ABI break, no justification, no mentioning either.
Again we are discussing basics of ABI breaking patches?

Best regards,
Krzysztof
