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

Hi everyone,

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.

Part 2 here includes patches from the v4.6 cycle, as well as additional
fixed found through Fixes tags:

9f8ea969d5cf PM / OPP: get/put regulators from OPP core
7d34d56ef334 PM / OPP: Disable OPPs that aren't supported by the regulator
655c9df96175 PM / OPP: Introduce dev_pm_opp_get_max_volt_latency()
2174344765f4 PM / OPP: Introduce dev_pm_opp_get_max_transition_latency()
50f8cfbd5897 PM / OPP: Parse clock-latency and voltage-tolerance for v1 bindings
d54974c2513f PM / OPP: Manage device clk
6a0712f6f199 PM / OPP: Add dev_pm_opp_set_rate()
896d6a4c0f41 cpufreq: dt: Convert few pr_debug/err() calls to dev_dbg/err()
457e99e60a8f cpufreq: dt: Rename 'need_update' to 'opp_v1'
391d9aef8145 cpufreq: dt: OPP layers handles clock-latency for V1 bindings as well
050794aaebbb cpufreq: dt: Pass regulator name to the OPP core
6def6ea75e6d cpufreq: dt: Unsupported OPPs are already disabled
755b888ff098 cpufreq: dt: Reuse dev_pm_opp_get_max_transition_latency()
78c3ba5df96c cpufreq: dt: Use dev_pm_opp_set_rate() to switch frequency
df2c8ec28e73 cpufreq: dt: No need to fetch voltage-tolerance
dd02a3d92008 cpufreq: dt: No need to allocate resources anymore
78ecc56247f0 PM / OPP: Fix NULL pointer dereference crash when disabling OPPs
0c717d0f9cb4 PM / OPP: Initialize regulator pointer to an error value
a5da64477ee7 PM / OPP: Fix incorrect comments
2c2709dc6921 PM / OPP: Rename structures for clarity
b318556479cc cpufreq: dt: Drop stale comment
21f8a99ce61b PM / OPP: Remove useless check
c5c2a97b3ac7 PM / OPP: Update voltage in case freq == old_freq

Of these,

b318556479cc cpufreq: dt: Drop stale comment

was found while looking through git logs.

21f8a99ce61b PM / OPP: Remove useless check
c5c2a97b3ac7 PM / OPP: Update voltage in case freq == old_freq

were found by looking for commit hashes in Fixes tags.
All other patches were included from TI's SDK.

The patches apply cleanly on top of linux-4.4.y-cip. The last patch
involved some backporting due to path and code changes between v4.6
and v4.18.

Please have a look.

Regards
ChenYu
