Pirot to that devfreq and devfreq-event framework defines the fixed 'devfreq'
and 'devfreq-event' property to get the devfreq/devfreq-event phandle. But,
these property name are not expressing the h/w. So, deprecate the fixed
property name of both 'devfreq' and 'devfreq-event'. But, in order to keep
the backward compatibility of devicetree, doesn't change the property name
on devfreq device drivers and devicetree.

This patchset picks only three patches from patchset[1].

[1] https://patchwork.kernel.org/cover/11304545/
- [v2,00/11] PM / devfreq: Remove deprecated 'devfreq' and 'devfreq-events' properties


Changes from v2:
- Send the patches related to both devfreq_get_devfreq_by_phandle
  and devfreq_event_get_edev_by_phandle function to change the function
  prototype.

Changes from v1:
- Edit function name by removing '_by_node' postfix.
- Split out dt-binding patch to make it the separte patch.
- Add Lukasz's tag for exynos5422-dmc

Chanwoo Choi (2):
  PM / devfreq: Change prototype of devfreq_get_devfreq_by_phandle function
  PM / devfreq: event: Change prototype of devfreq_event_get_edev_by_phandle function

Leonard Crestez (1):
  PM / devfreq: Add devfreq_get_devfreq_by_node function
