Hello!
All the errors that you've pointed out have been fixed on both the CPR,
CPR3 and cpufreq-hw, but before pushing a V2 of this patch series...

Well, I have a question: the qcom-cpufreq-hw driver has no MAINTAINERS
entry and there was no maintainer for this driver specified in the old
txt format binding.

What should I write in the "maintainers" field of the YAML binding for
this driver?
Should I assign it to the subsystem maintainer?

Thanks,
- Angelo
