description:
  The Periodic Interval Timer (PIT) is part of the System Controller of
  various Microchip 32-bit ARM-based SoCs (formerly Atmel AT91 series).
  It is a simple down-counter timer used mainly as the kernel tick source.
  The PIT is clocked from the slow clock and shares a single IRQ line with
  other System Controller peripherals.
