[PATCH 0/7] hisi_sas: Add runtime PM support for v3 hw

From: John Garry
Date: Fri Oct 02 2020 - 10:34:45 EST


This series adds runtime PM support for v3 hw. Consists of:
- Switch to new PM suspend and resume framework
- Add links to devices to ensure host cannot be suspended while devices
are not
- Filter out phy events during suspend to avoid deadlock
- Add controller RPM support
- And some more minor misc related changes

I also included a random small fix, only visible when #CPUs < #queues and
MSI affinity module param set.

Note that this series does not conflict with patch "scsi: hisi_sas:
Switch v3 hw to MQ", which is supposed to go through the block tree:
