  interrupt number is the rtc alarm interrupt and second interrupt number

  is the rtc tick interrupt. The number of cells representing a interrupt

  depends on the parent interrupt controller.

          and source clocks.

- clock-names: Must contain "rtc" and "rtc_src" entries sorted in the

               same order as the clocks property.
