-Marvell ICU Interrupt Controller
---------------------------------
-
-The Marvell ICU (Interrupt Consolidation Unit) controller is
-responsible for collecting all wired-interrupt sources in the CP and
-communicating them to the GIC in the AP, the unit translates interrupt
-requests on input wires to MSG memory mapped transactions to the GIC.
-
-Required properties:
-
-- compatible: Should be "marvell,cp110-icu"
-
-- reg: Should contain ICU registers location and length.
-
-- #interrupt-cells: Specifies the number of cells needed to encode an
-  interrupt source. The value shall be 3.
-
-  The 1st cell is the group type of the ICU interrupt. Possible group
-  types are:
-
-   ICU_GRP_NSR (0x0) : Shared peripheral interrupt, non-secure
-   ICU_GRP_SR  (0x1) : Shared peripheral interrupt, secure
-   ICU_GRP_SEI (0x4) : System error interrupt
-   ICU_GRP_REI (0x5) : RAM error interrupt
-
-  The 2nd cell is the index of the interrupt in the ICU unit.
-
-  The 3rd cell is the type of the interrupt. See arm,gic.txt for
-  details.
-
-- interrupt-controller: Identifies the node as an interrupt
-  controller.
-
-- msi-parent: Should point to the GICP controller, the GIC extension
-  that allows to trigger interrupts using MSG memory mapped
-  transactions.
-
-Example:
-
-icu: interrupt-controller@1e0000 {
-	compatible = "marvell,cp110-icu";
-	reg = <0x1e0000 0x10>;
-	#interrupt-cells = <3>;
-	interrupt-controller;
-	msi-parent = <&gicp>;
-};
-
-usb3h0: usb3@500000 {
-	interrupt-parent = <&icu>;
-	interrupts = <ICU_GRP_NSR 106 IRQ_TYPE_LEVEL_HIGH>;
-};
