title: Atmel Power Management Controller (PMC)

maintainers:
  - Claudiu Beznea <claudiu.beznea@microchip.com>

description:
  The power management controller optimizes power consumption by controlling all
  system and user peripheral clocks. The PMC enables/disables the clock inputs
  to many of the peripherals and to the processor.
