    1 Marvell Armada 7K/8K PIC Interrupt controller
    2 ---------------------------------------------
    3 
    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>;
   25         };
