This is the final part of MOXA's PM / OPP / ti-cpufreq backport series.
Part 2, which consisted of OPP / cpufreq-dt cleanups, is abandoned in
favor of directly backporting the ti-cpufreq driver.
This part includes a couple of patches to the PM / OPP subsystem to
expose required APIs, and deal with the v1/v2 mixed OPP table used
by am33xx. The rest are the backport of the ti-cpufreq driver, and
fixes for this driver. The fixes were requested by CIP kernel
maintainers as part of MOXA's previous attempt to backport ti-cpufreq.
They are included as separate patches, as there are quite a few of them
spread over multiple kernel releases.
The result is that my BeagleBone Black can run at higher speeds than
without the ti-cpufreq driver due to having a better silicon revision.
Please have a look.
