Subject: [PATCH net v2 0/2] net: ipa: enable register retention

With runtime power management in place, we sometimes need to issue
a command to enable retention of IPA register values before power
collapse.  This requires a new Device Tree property, whose presence
will also be used to signal that the command is required.

Version 2 is exactly the same as version 1, but this version is
also being sent to the devicetree mailing list.
