1Freescale IRQSTEER Interrupt multiplexer
2
3Required properties:
4
5- compatible: should be:
6	- "fsl,imx8m-irqsteer"
7	- "fsl,imx-irqsteer"
8- reg: Physical base address and size of registers.
9- interrupts: Should contain the up to 8 parent interrupt lines used to
10  multiplex the input interrupts. They should be specified sequentially
11  from output 0 to 7.
12- clocks: Should contain one clock for entry in clock-names
13  see Documentation/devicetree/bindings/clock/clock-bindings.txt
14- clock-names:
15   - "ipg": main logic clock
16- interrupt-controller: Identifies the node as an interrupt controller.
17- #interrupt-cells: Specifies the number of cells needed to encode an
18  interrupt source. The value must be 1.
19- fsl,channel: The output channel that all input IRQs should be steered into.
20- fsl,num-irqs: Number of input interrupts of this channel.
21  Should be multiple of 32 input interrupts and up to 512 interrupts.

23Example:

25	interrupt-controller@32e2d000 {
26		compatible = "fsl,imx8m-irqsteer", "fsl,imx-irqsteer";
27		reg = <0x32e2d000 0x1000>;
28		interrupts = <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
29		clocks = <&clk IMX8MQ_CLK_DISP_APB_ROOT>;
30		clock-names = "ipg";
31		fsl,channel = <0>;
32		fsl,num-irqs = <64>;
33		interrupt-controller;
34		#interrupt-cells = <1>;
35	};
