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
