[PATCH V3 0/6] PM / OPP: Add debugfs support

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

Hi Rafael,

This is (hopefully) the last version of this patchset, all the patches
are reviewed by Stephen (Many thanks for this) now and sending
everything again so that you know exactly what all to apply.

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.

V2-Resend->V3:
- 2/6 is a new patch
- 3/6 also modifies of_add_opp_table() now..
- Reviewed by tags from Stephen

V2->V2-Resend:
- V2 1/6 is dropped as its already merged, rest unchanged.

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).
