[PATCH 3/3] PM / Domains: Add support for PM domain on/off notifiers for genpd

2020-08-19 Thread Ulf Hansson
A device may have specific HW constraints that must be obeyed to, before its corresponding PM domain (genpd) can be powered off - and vice verse at power on. These constraints can't be managed through the regular runtime PM based deployment for a device, because the access pattern for it, isn't
