From: Daniel Baluta daniel.baluta@nxp.com
i.MX8QXP/i.MX8QM has IPs that need multiple power domains to be up in order to work. 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.
