My understanding is that there is very little use of any of this
upstream since it's all pretty new, some platforms have OPPs but use a
firmware interface rather than the OS to control clocks and regulators
while most other platforms don't have OPPs defined and it's only
platforms with both regulators and OPPs that are affected.
