 11title: Marvell ICU Interrupt Controller
 12
 13description:
 14  The Marvell ICU (Interrupt Consolidation Unit) controller is responsible for
 15  collecting all wired-interrupt sources in the CP and communicating them to the
 16  GIC in the AP. The unit translates interrupt requests on input wires to MSG
 17  memory mapped transactions to the GIC. These messages access different GIC
 18  memory areas depending on their type (NSR, SR, SEI, REI, etc).
