+J-Core Advanced Interrupt Controller
+
+Required properties:
+
+- compatible: Should be "jcore,aic1" for the (obsolete) first-generation aic
+ with 8 interrupt lines with programmable priorities, or "jcore,aic2" for
+ the "aic2" core with 64 interrupts.
+
+- reg: Memory region(s) for configuration. For SMP, there should be one
+ region per cpu, indexed by the sequential, zero-based hardware cpu
+ number.
+
+- interrupt-controller: Identifies the node as an interrupt controller
+
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 1.
+
+
+Example:
+
+aic: interrupt-controller@200 {
+ compatible = "jcore,aic2";
+ reg = < 0x200 0x30 0x500 0x30 >;
+ interrupt-controller;
+ #interrupt-cells = <1>;

+Marvell Armada 7K/8K PIC Interrupt controller
+---------------------------------------------
+
+This is the Device Tree binding for the PIC, a secondary interrupt
+controller available on the Marvell Armada 7K/8K ARM64 SoCs, and
+typically connected to the GIC as the primary interrupt controller.
+
+Required properties:
+- compatible: should be "marvell,armada-8k-pic"
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: the number of cells to define interrupts on this
+ controller. Should be 1
+- reg: the register area for the PIC interrupt controller
+- interrupts: the interrupt to the primary interrupt controller,
+ typically the GIC
+
+Example:
+
+ pic: interrupt-controller@3f0100 {
+ compatible = "marvell,armada-8k-pic";
+ reg = <0x3f0100 0x10>;
+ #interrupt-cells = <1>;
+ interrupt-controller;
+ interrupts = <GIC_PPI 15 IRQ_TYPE_LEVEL_HIGH>;
+ };
