[PATCH 0/2] allow cpufreq drivers to export flags
From: Mike Turquette
Date: Wed Oct 08 2014 - 03:50:07 EST
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.
