Stats comparision between OSI and PC mode are captured at [3] with usecase details, where during multiple CPUs online the residency in cluster idle state is better with OSI and also inline with single CPU mode. In PC mode with multiple CPUs cluster idle state residency is dropping compare to single CPU mode. Recording of this meeting is also available at [4]. This change adds power-domains for cpuidle states to use PSCI OS initiated mode for sc7280. This change depends on external project changes [1] & [2] which are under review/discussion to add PSCI os-initiated support in Arm Trusted Firmware. I can update here once the dependency are in and change is ready to merge.
