Hi Rafael,

This is mostly reviewed and its been out on the lists for around one and
half month. We can get it pushed for 4.3 now. Resending the series
because of minor updates in few patches, which were also sent as replies
to earlier version.

I have tested this on dual-core exynos board with the driver inbuilt as
well as a module. Tried multiple insertion/removals of the module. Have
tested cpufreq-dt driver with both old and new bindings.


This adds code to support operating-points-v2 bindings. Not everything
is supported yet, but most of the basic stuff is.

Pushed here as well for reference:
ssh://git@git.linaro.org/people/viresh.kumar/linux.git opp/v2

- 1/11 is a new patch which moves the bindings file into opp specific
- 'opp-suspend' binding got updated and is part of individual OPPs now,
  instead of a phandle present in the opp table.
- Some more minor reformatting as suggested by Bartlomiej and Stephen,
  they were already posted as reply to earlier patches in V1.
