1Marvell Armada 7K/8K PIC Interrupt controller
2---------------------------------------------
3
4This is the Device Tree binding for the PIC, a secondary interrupt
5controller available on the Marvell Armada 7K/8K ARM64 SoCs, and
6typically connected to the GIC as the primary interrupt controller.
7
8Required properties:
9- compatible: should be "marvell,armada-8k-pic"
10- interrupt-controller: identifies the node as an interrupt controller
11- #interrupt-cells: the number of cells to define interrupts on this
12  controller. Should be 1
13- reg: the register area for the PIC interrupt controller
14- interrupts: the interrupt to the primary interrupt controller,
15  typically the GIC
16
17Example:
18
19	pic: interrupt-controller@3f0100 {
20		compatible = "marvell,armada-8k-pic";
21		reg = <0x3f0100 0x10>;
22		#interrupt-cells = <1>;
23		interrupt-controller;
24		interrupts = <GIC_PPI 15 IRQ_TYPE_LEVEL_HIGH>;
25	};
