dt-bindings: interrupt-controller: Convert marvell,armada-8k-pic to DT schema
Convert the Marvell 7K/8K PIC interrupt controller binding to schema
format. It's a straight-forward conversion of the typical interrupt
controller.

---------------------------------------------

-
4
-
This is the Device Tree binding for the PIC, a secondary interrupt
5
-
controller available on the Marvell Armada 7K/8K ARM64 SoCs, and
6
-
typically connected to the GIC as the primary interrupt controller.
7
-
8
-
Required 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
-
17

Example:
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>;
