Is this supposed to be RPS_MAX_FREQ_MHZ?
We could do this check for max as well. But this is trying to see if min
can be set to below rpn.

After addressing the above, this is:

Also, before merging it would be good to see the results of the new
tests. So could you add a HAX patch adding the new tests to
fast-feedback.testlist and resend the series?
Sure, will do. Thanks for the review.
Vinay.
Thanks.
