Everything upstream should be for post-silicon. I've seen and done the hacks to make pre-silicon testing work and we don't need those upstream. > + clock period in nanoseconds, when the hardware set default does not match If you have units, then use property unit suffix in the name. > + the actual clock. > + $ref: /schemas/types.yaml#/definitions/uint32 And then you can drop the type. However, if the h/w block gets a ref clock why isn't it described in 'clocks' and then you can just read why the frequency is and calculate the period.
