This series adds the throttler driver, for non-thermal throttling of
CPUs and devfreq devices. A use case for non-thermal throttling could
be the detection of a high battery discharge voltage, close to the
over-current protection (OCP) limit of the battery.

To support throttling of devfreq devices the series introduces the
concept of a devfreq policy and the DEVFREQ_ADJUST notifier (similar
to CPUFREQ_ADJUST). Further it includes some related devfreq bugfixes
and improvements that change some of the code that is also touched
by the policy changes.

Matthias Kaehlcke (11):
  PM / devfreq: Init user limits from OPP limits, not viceversa
  PM / devfreq: Fix handling of min/max_freq == 0
  PM / devfreq: Don't adjust to user limits in governors
  PM / devfreq: Add struct devfreq_policy
  PM / devfreg: Add support for policy notifiers
  PM / devfreq: Make update_devfreq() public
  PM / devfreq: export devfreq_class
  dt-bindings: PM / OPP: add opp-throttlers property
  misc: throttler: Add core support for non-thermal throttling
  dt-bindings: misc: add bindings for cros_ec_throttler
  misc: throttler: Add Chrome OS EC throttler
