this looks rather odd, you have two entries in the table that point to
the exact same pair of firmware and topology files. This is either
intentional and missing a comment, or a copy-paste mistake, or some of
these fields are not required.

mclk and wclk are different concepts usually.

I wonder if soc_mclk means 'soc_clock_provider' ?

it looks like a configuration instead of a real/physical clock?
