Subject[RFC 0/3] cpuidle/powernv: Interface to handle idle-stop versioning
Date
A design patch series illuminates the idea of handling different
versions of idle-stop, the properties they support and the
quirks that need to be handled before entering or after exiting stop.

It also adds a functionality to identify firmware-enabled-stop and set
the according bits to encapsulate the support and corresponding handling

Corresponding RFC skiboot patch: https://lists.ozlabs.org/pipermail/skiboot/2020-March/016552.html

Pratik Rajesh Sampat (3):
Interface for an idle-stop dependency structure
Demonstration of handling an idle-stop quirk version
Introduce capability for firmware-enabled-stop
