[PATCH 0/2] cpuidle: psci: Enable s2idle when using PSCI OSI

When using PSCI OSI together with the PM domain topology, the domain idle
states becomes selected via calls to pm_runtime_put_sync_suspend(). This works
fine for the regular idle path, but not for system wide suspend-to-idle.

This problem is because runtime PM gets disabled by the PM core, during system
wide suspend. In this small series, these issues are being fixed.

Kind regards
Ulf Hansson
