Re: [PATCH 4.4.y-cip 00/23] PM / OPP v2 & cpufreq backports part 2

Hi!

This is part 2 of MOXA's PM / OPP / cpufreq backport series. The whole
series aims to backport patches related to PM / OPPv2 and cpufreq
which were included in the v4.4 kernel from TI's SDK. The end goal is
to include cpufreq-ti and convert am33xx to using it and OPPv2.
Ok, I went through them, and most of them are ok.

OTOH lots of them are changing common code, and I don't believe all of
them are neccessary for am33xx support.

Could you identify changes that are not neccesary for am33xx support,
and drop those?
So I tried just backporting the ti-cpufreq driver. However as the am33xx
OPP table wasn't completely converted to the v2 format, missing the
clock-latency-ns property, it is unusable in this standalone state.

A couple of patches for PM/OPP are needed:

0764c604c812 PM / OPP: Expose _of_get_opp_desc_node as dev_pm_opp API
50f8cfbd5897 PM / OPP: Parse clock-latency and voltage-tolerance
for v1 bindings

I suppose this would be preferred over backporting all the OPP / PM
cleanups?
Yes, that seems to be better solution than the previous series.

Best regards,
Pavel
