Merge branches 'pm-sleep' and 'pm-runtime'

* pm-sleep:
  PM / sleep: trace_device_pm_callback coverage in dpm_prepare/complete
  PM / wakeup: add a dummy wakeup_source to record statistics
  PM / sleep: Make suspend-to-idle-specific code depend on CONFIG_SUSPEND
  PM / sleep: Return -EBUSY from suspend_enter() on wakeup detection
  PM / tick: Add tracepoints for suspend-to-idle diagnostics
  PM / sleep: Fix symbol name in a comment in kernel/power/main.c
  leds / PM: fix hibernation on arm when gpio-led used with CPU led trigger
  ARM: omap-device: use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
  bus: omap_l3_noc: add missed callbacks for suspend-to-disk
  PM / sleep: Add macro to define common noirq system PM callbacks
  PM / sleep: Refine diagnostic messages in enter_state()
  PM / wakeup: validate wakeup source before activating it.

* pm-runtime:
  PM / Runtime: Update last_busy in rpm_resume
  PM / runtime: add note about re-calling in during device probe()
