13description:
14  The Microchip PIT64B is a 64-bit periodic interval timer used in
15  several modern Microchip ARM SoCs including SAM9X60, SAM9X7 and
16  SAMA7D65 families. It provides extended timing range, flexible
17  clock selection and supports both periodic and one-shot interrupt
18  generation modes.
