Subject: [PATCH 0/2] allow cpufreq drivers to export flags

This series is partially in response to a discussion around DT bindings
for CPUfreq drivers [0], but it is also needed for on-going work to
integrate CPUfreq with the scheduler. In particular a scheduler-driven
cpu frequency scaling policy would be well served to know if the
underlying CPUfreq driver .target callback might sleep or block for a
long time.

Mike Turquette (2):
  cpufreq: add driver flag for sleepable transitions
  cpufreq: new function to query driver for flags
