So, what are those requirements, which could not be matched with
cpufreq-dt? We should really try to not add another cpufreq driver.

I don't see anything special in here. A single regulator and some clocks
needing to be controlled in the right way. That's already handled for
i.MX5 with cpufreq-dt. Please look up how it is done there and try to do
it the same way for MX7, or provide substantial information why it
couldn't be done.

Lucas
