I believe these two clocks are mandatory?

minItems default is equal to items numbers, here is 4. So all 4 clock are
mandatory.

Anything wrong here?

I'd say that the two "bch" clocks are only used if you decide to
configure the on-host hardware ECC engine and thus are not needed with
software corrections, but I'm fine keeping the fourth described in all
cases if that's simpler.

Also,here the diff just shows that "if we provide a clocks property
with this compatible, then we need to provide 4 members", I believe the
"required" property is already filled somewhere with the
clocks/clock-names properties?

Thanks,
Miquèl
