[PATCH v5 0/2] PM / Domains: Add support for 'required-opps' to set default perf state

[Rajendra Nayak]

v5: Dropped all default_pstate handling in runtime suspend/resume

v4: Fixed error handling in __genpd_dev_pm_attach()

This is a re-spin of the series [1] which was adding support for a new
DT binding (assigned-performance-state) and based on the discussions on
that thread [2] it was concluded that we could achieve the same with the
existing 'required-opps' binding instead.

So this series, just drops the new binding and uses required-opps to achieve
the default perf state setting thats needed by some devices.

---
Some devics within power-domains with performance states do not
support DVFS, but still need to vote on a default/static state
while they are active. Add support for this using the 'required-opps'
property in device tree.
