I am assuming you are lost because of reviewing too many similar
patches, but anyway below was part of the diff and so resume was
required :)

-       switch (mode) {
-       case CLOCK_EVT_MODE_RESUME:
-       case CLOCK_EVT_MODE_ONESHOT:
-               /* Enable timer interrupts */
-               writel(TIMER_INTR_MSK, timer->interrupt_regs + IO_INTR_MSK);
-               writel(TIMER_INTR_ALL, timer->interrupt_regs + IO_INTR_ACK);
-               break;
