On Marvell Berlin SoCs, the cpu's local timer is shutdown when the cpu goes to a deep idle state, then the timer framework will be notified to use a broadcast timer instead. The broadcast timer uses dw-apb-ictl as interrupt chip, these patches try to add irq_set_affinity support so that the going to deep idle state cpu can set the interrupt affinity of the broadcast interrupt to avoid unnecessary wakeups and IPIs.
