1 Marvell ICU Interrupt Controller
2 --------------------------------
4 The Marvell ICU (Interrupt Consolidation Unit) controller is
5 responsible for collecting all wired-interrupt sources in the CP and
6 communicating them to the GIC in the AP, the unit translates interrupt
13 - compatible: Should be "marvell,cp110-icu"
15 - reg: Should contain ICU registers location and length.
17 Subnodes: Each group of interrupt is declared as a subnode of the ICU,
22 - compatible: Should be one of:
23               * "marvell,cp110-icu-nsr"
24 	      * "marvell,cp110-icu-sr"
25 	      * "marvell,cp110-icu-sei"
26 	      * "marvell,cp110-icu-rei"
28 - #interrupt-cells: Specifies the number of cells needed to encode an
29   interrupt source. The value shall be 2.
31   The 1st cell is the index of the interrupt in the ICU unit.
33   The 2nd cell is the type of the interrupt. See arm,gic.txt for
36 - interrupt-controller: Identifies the node as an interrupt
37   controller.
39 - msi-parent: Should point to the GICP controller, the GIC extension

85 The legacy bindings were different in this way:
87 - #interrupt-cells: The value was 3.
88 	The 1st cell was the group type of the ICU interrupt. Possible
90 	ICU_GRP_NSR (0x0) : Shared peripheral interrupt, non-secure
91 	ICU_GRP_SR  (0x1) : Shared peripheral interrupt, secure
92 	ICU_GRP_SEI (0x4) : System error interrupt
93 	ICU_GRP_REI (0x5) : RAM error interrupt
94 	The 2nd cell was the index of the interrupt in the ICU unit.
95 	The 3rd cell was the type of the interrupt. See arm,gic.txt for
100 icu: interrupt-controller@1e0000 {

104 	#interrupt-cells = <3>;
105 	interrupt-controller;
106 	msi-parent = <&gicp>;
110 	interrupt-parent = <&icu>;
