In order to help drivers, we introduce multi PM domains helpers that are able to activate/deactivate multi PM domains. First patch introduces the helpers and second patch demonstrates how a driver can use them instead of hardcoding the PM domains handling. Changes since v2: » - fix kernel test robot reported issues (missing static inline for newly introduced functions in headers and arguments swapped for devm_kzalloc). Changes since v1: (addressed Ranjani's comments) » - enhanced description for dev_multi_pm_attach return value » - renamed exit_unroll_pm label to exit_detach_pm Ideally would be to have patch 1/2 merged via power tree and then I will submit again patch 2/2 on sound tree.
