   12 description:
   13   The DB8500 Power Reset and Control Management Unit is an XP70 8-bit
   14   microprocessor that is embedded in the always-on power domain of the
   15   DB8500 SoCs to manage the low power states, powering up and down parts
   16   of the silicon, and controlling reset of different IP blocks.

   25       compatible is needed for the device to be exposed as a system
   26       controller so that arbitrary registers can be access by
   27       different operating system components.
