Changes since v1 [2] -
- Addressed review comments from v1.
- Fixes around dynamic allocation of genpd states
- Used OF method for iterating phandles
- Updated documentation, examples

- The series is available at [3].

The changes from [1] are -
- Allocating memory for domain idle states dynamically
- Conform to naming conventions for internal and exported genpd functions
- DT binding example for domain-idle-state
- Use fwnode instead of of_node
- Handle atomic case for removal of PM Domain
- Rebase on top of Rafael's pm/genpd tree

Thanks,
Lina

Rafael, Lina,

This looks good to me! Unless any other objections, I suggest to apply this to get it tested in linux-next.
