Subject: [PATCH RESEND 4.4.y-cip 00/15] PM / OPP v2 & cpufreq backports part 1

Hi everyone,

This is part 1 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.

Part 1 here includes patches from the v4.5 cycle, listed in topological
order:

deaa51465105 PM / OPP: Add debugfs support
1c4d12de2719 PM / OPP: Add "opp-supported-hw" binding
ffdb8cc7a27c PM / OPP: Add {opp-microvolt|opp-microamp}-<name> binding
af87a39a5f7c PM / OPP: Remove 'operating-points-names' binding
754dcf35f346 PM / OPP: Rename OPP nodes as opp@<opp-hz>
dc4e7b1fa20a PM / OPP: Add missing doc comments
7de36b0aa51a PM / OPP: Parse 'opp-supported-hw' binding
01fb4d3c39d3 PM / OPP: Parse 'opp-<prop>-<name>' bindings
fd8d8e63467c PM / OPP: Fix parsing of opp-microvolt and opp-microamp properties
d9de19b1cc01 PM / OPP: Set cpu_dev->id in cpumask first
5ff24d601092 PM / OPP: Use snprintf() instead of sprintf()
3be3f8f36e73 devicetree: bindings: Add optional dynamic-power-coefficient property
f8fa8ae06b8c cpufreq-dt: Supply power coefficient when registering cooling devices
929ca89c305a cpufreq-dt: fix handling regulator_get_voltage() result
b331bc20d928 cpufreq: cpufreq-dt: avoid uninitialized variable warnings:

Of these,

dc4e7b1fa20a PM / OPP: Add missing doc comments

was identified as a patch dependency, but otherwise serves no purpose. And

d9de19b1cc01 PM / OPP: Set cpu_dev->id in cpumask first

was found while looking through git logs. Last,

3be3f8f36e73 devicetree: bindings: Add optional dynamic-power-coefficient property

is related to

f8fa8ae06b8c cpufreq-dt: Supply power coefficient when registering cooling devices

All other patches were included from TI's SDK.

The patches apply cleanly on top of linux-4.4.y-cip. Please have a look.
I have nothing to point out other than the comment on "PM / OPP: Set cpu_dev->id in cpumask first".
