+Hisilicon mbigen device tree bindings.
+=======================================
+
+Mbigen means: message based interrupt generator.
+
+MBI is kind of msi interrupt only used on Non-PCI devices.
+
+To reduce the wired interrupt number connected to GIC,
+Hisilicon designed mbigen to collect and generate interrupt.
+
+
+Non-pci devices can connect to mbigen and generate the
+interrupt by writing ITS register.
+
+The mbigen chip and devices connect to mbigen have the following properties:
+
+Mbigen main node required properties:
+-------------------------------------------
+- compatible: Should be "hisilicon,mbigen-v2"
+
+- reg: Specifies the base physical address and size of the Mbigen
+  registers.
+
+- interrupt controller: Identifies the node as an interrupt controller
+
+- msi-parent: Specifies the MSI controller this mbigen use.
+  For more detail information,please refer to the generic msi-parent binding in
+  Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+- num-pins: the total number of pins implemented in this Mbigen
+  instance.
+
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source. The value must be 2.
+
+  The 1st cell is hardware pin number of the interrupt.This number is local to
+  each mbigen chip and in the range from 0 to the maximum interrupts number
+  of the mbigen.
+
+  The 2nd cell is the interrupt trigger type.
+	The value of this cell should be:
+	1: rising edge triggered
+	or
+	4: high level triggered
+
+Examples:
+
+	mbigen_device_gmac:intc {
+			compatible = "hisilicon,mbigen-v2";
+			reg = <0x0 0xc0080000 0x0 0x10000>;
+			interrupt-controller;
+			msi-parent = <&its_dsa 0x40b1c>;
+			num-pins = <9>;
+			#interrupt-cells = <2>;
+	};
+
+Devices connect to mbigen required properties:
+----------------------------------------------------
+-interrupt-parent: Specifies the mbigen device node which device connected.
+
+-interrupts:Specifies the interrupt source.
+ For the specific information of each cell in this property,please refer to
+ the "interrupt-cells" description mentioned above.
+
+Examples:
+	gmac0: ethernet@c2080000 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0 0xc2080000 0 0x20000>,
+		      <0 0xc0000000 0 0x1000>;
+		interrupt-parent  = <&mbigen_device_gmac>;
+		interrupts =	<656 1>,
+				<657 1>;

+Microchip PIC32 Interrupt Controller
+====================================
+
+The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
+It handles all internal and external interrupts. This controller exists outside
+of the CPU and is the arbitrator of all interrupts (including interrupts from
+the CPU itself) before they are presented to the CPU.
+
+External interrupts have a software configurable edge polarity. Non external
+interrupts have a type and polarity that is determined by the source of the
+interrupt.
+
+Required properties
+-------------------
+
+- compatible: Should be "microchip,pic32mzda-evic"
+- reg: Specifies physical base address and size of register range.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt cells: Specifies the number of cells used to encode an interrupt
+  source connected to this controller. The value shall be 2 and interrupt
+  descriptor shall have the following format:
+
+	<hw_irq irq_type>
+
+  hw_irq - represents the hardware interrupt number as in the data sheet.
+  irq_type - is used to describe the type and polarity of an interrupt. For
+  internal interrupts use IRQ_TYPE_EDGE_RISING for non persistent interrupts and
+  IRQ_TYPE_LEVEL_HIGH for persistent interrupts. For external interrupts use
+  IRQ_TYPE_EDGE_RISING or IRQ_TYPE_EDGE_FALLING to select the desired polarity.
+
+Optional properties
+-------------------
+- microchip,external-irqs: u32 array of external interrupts with software
+  polarity configuration. This array corresponds to the bits in the INTCON
+  SFR.
+
+Example
+-------
+
+evic: interrupt-controller@1f810000 {
+	compatible = "microchip,pic32mzda-evic";
+	interrupt-controller;
+	#interrupt-cells = <2>;
+	reg = <0x1f810000 0x1000>;
+	microchip,external-irqs = <3 8 13 18 23>;
+};
+
+Each device/peripheral must request its interrupt line with the associated type
+and polarity.
+
+Internal interrupt DTS snippet
+------------------------------
+
+device@1f800000 {
+	...
+	interrupts = <113 IRQ_TYPE_LEVEL_HIGH>;
+	...

+External interrupt DTS snippet
+------------------------------
+
+device@1f800000 {
+	...
+	interrupts = <3 IRQ_TYPE_EDGE_RISING>;
