[PATCH V2 0/6] PM / OPP: Add debugfs support

[Viresh Kumar <viresh.kumar@linaro.org>]

Hi Guys,

This isn't necessarily 4.3 material, but its fine if it can hit 4.3 :).

This series is targeted towards exposing opp information at user space.
I wasn't really sure about adding them to sysfs, as its mostly static
(fixed) data and so debugfs looked to be better place.

This series starts with 3 cleanup patches, and then moves all opp stuff
to a new directory as its expanding enough now.

The last patch adds debugfs support for OPPs and works for both old and
new v2 bindings.

Rebased over: pm/bleeding-edge branch.

V1->V2:
- Moved the second patch to the top as its a fix (Dan Carpenter &
  Stephen).
- Also updated it to fix things properly.
- rearranged opp entry in drivers/base/power/Makefile (Stephen)
- Device-directory name also includes its parent name now, to make it
  more unique (Stephen).
- Migrate debugfs directory properly if unregistered for the owner
  device (Stephen).

Viresh Kumar (6):
  PM / OPP: Free resources and properly return error on failure
  PM / OPP: reuse of_parse_phandle()
  PM / OPP: Prefix exported opp routines with dev_pm_opp_
  PM / OPP: Move opp core to its own directory
  PM / OPP: Move cpu specific code to opp/cpu.c
  PM / OPP: Add debugfs support
