Pull documentation update from Jonathan Corbet:
 "A reasonably busy cycle for documentation this time around. There is a
  new guide for user-space API documents, rather sparsely populated at
  the moment, but it's a start. Markus improved the infrastructure for
  converting diagrams. Mauro has converted much of the USB documentation
  over to RST. Plus the usual set of fixes, improvements, and tweaks.

  There's a bit more than the usual amount of reaching out of
  Documentation/ to fix comments elsewhere in the tree; I have acks for
  those where I could get them"

Document the fact that the autosuspend delay and enable helpers may
change the power.usage_count and resume or suspend a device depending on
the values of power.autosuspend_delay and power.use_autosuspend.

Note that this means that a driver must disable autosuspend before
disabling runtime pm on probe errors and on driver unbind if the device
is to be suspended upon return (as a negative delay may otherwise keep
the device resumed).

<id>72ec2e17f9f7f7f6082ec57183080726eb3523e3</id>
<content type='text'>
Update the autosuspend documentation which claimed that the autosuspend
delay is not taken into account when using the non-autosuspend helper
functions, something which is no longer true since commit d66e6db28df3
("PM / Runtime: Respect autosuspend when idle triggers suspend").

This specifically means that drivers must now disable autosuspend before
disabling runtime pm in probe error paths and remove callbacks if
pm_runtime_put_sync was being used to suspend the device before
returning. (If an idle callback can prevent suspend,
pm_runtime_put_sync_suspend must be used instead of pm_runtime_put_sync
as before.)

Also remove the claim that the autosuspend helpers behave "just like
the non-autosuspend counterparts", something which have never really
been true as some of the latter use idle notifications.

Pull more power management updates deom Rafael Wysocki:
 "These fix two bugs introduced by recent power management updates (in
  the cpuidle menu governor and intel_pstate) and a few other issues,
  clean up things and remove unused code.

  Specifics:

   - Fix for a cpuidle menu governor problem that started to take an
     unnecessary spinlock after one of the recent updates and that did
     not play well with the RT patch (Rafael Wysocki).

   - Fix for the new intel_pstate operation mode switching feature added
     recently that did not reinitialize P-state limits properly when
     switching operation modes (Rafael Wysocki).

   - Removal of unused global notifiers from the PM QoS framework
     (Viresh Kumar).

   - Generic power domains framework update to make it handle
     asynchronous invocations of PM callbacks in the "noirq" phases of
     system suspend/hibernation correctly (Ulf Hansson).

   - Two hibernation core cleanups (Rafael Wysocki).

   - intel_idle cleanup related to the sysfs interface (Len Brown).

   - Off-by-one bug fix in the OPP (Operating Performance Points)
     framework (Andrzej Hajda).

   - OPP framework's documentation fix (Viresh Kumar).

   - cpufreq qoriq driver cleanup (Tang Yuantian).

   - Fixes for typos in comments in the device runtime PM framework
     (Christophe Jaillet)"
