Subject: [RFC 0/3] cpuidle/powernv: Interface to handle idle-stop versioning
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
