Paul Burton 06abee685c clocksource: mips-gic-timer: Enable counter when CPUs start ... [ Upstream commit 3128b0a2e0 ] In multi-cluster MIPS I6500 systems there is a GIC in each cluster, each with its own counter. When a cluster powers up the counter will be stopped, with the COUNTSTOP bit set in the GIC_CONFIG register. In single cluster systems, it has been fine to clear COUNTSTOP once in gic_clocksource_of_init() to start the counter. In multi-cluster systems, this will only have started the counter in the boot cluster, and any CPUs in other clusters will find their counter stopped which will break the GIC clock_event_device. Resolve this by having CPUs clear the COUNTSTOP bit when they come online, using the existing gic_starting_cpu() CPU hotplug callback. This will allow CPUs in secondary clusters to ensure that the cluster's GIC counter is running as expected.
