[RFC PATCH 0/2] Introduce multi PM domains helpers

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.
