However, the default affinity is set to cpu 0. This timer will be used as broadcast timer on all the i.MX SoCs. Because DYNIRQ flag is set, the core time framework will runtime set the interrupt affinity to the cores that needs to wake up and the cpumask will runtime set to the core that will be wake up. So even the sysctr initialization use cpumask 0, there is no issue, the current patch is just use cpu_possible_mask to show the fact that the timer supports routed to all the cpu cores and nothing else.
