  PM / devfreq: Don't adjust to user limits in governors
  PM / devfreq: Fix handling of min/max_freq == 0
  PM / devfreq: Drop custom MIN/MAX macros
  PM / devfreq: Fix devfreq_add_device() when drivers are built as modules.

* pm-tools:
  PM / tools: sleepgraph and bootgraph: upgrade to v5.2
  PM / tools: sleepgraph: first batch of v5.2 changes
  cpupower: Fix coredump on VMWare
  cpupower: Fix AMD Family 0x17 msr_pstate size
  cpupower: remove stringop-truncation waring
