The unit is mV/ns. 0 is the slowest, and 7 is the fastest.- $ref: /schemas/types.yaml#/definitions/uint32

I meant make the property in terms of the unit, so nuvoton,dmic-slew-rate-volt-per-sec (or similar, Rob would likely know better how he likes the unit suffix for a more complex unit like this one) and then make it an enum with possible values corresponding to the real values that putting 0, 1, 2, 3 etc into the register produces.
Cheers, Conor.
