-Freescale IRQSTEER Interrupt multiplexer
-
-Required properties:
-
-- compatible: should be:
-	- "fsl,imx8m-irqsteer"
-	- "fsl,imx-irqsteer"
-- reg: Physical base address and size of registers.
-- interrupts: Should contain the up to 8 parent interrupt lines used to
-  multiplex the input interrupts. They should be specified sequentially
-  from output 0 to 7.
-- clocks: Should contain one clock for entry in clock-names
-  see Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names:
-   - "ipg": main logic clock
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
-  interrupt source. The value must be 1.
-- fsl,channel: The output channel that all input IRQs should be steered into.
-- fsl,num-irqs: Number of input interrupts of this channel.
-  Should be multiple of 32 input interrupts and up to 512 interrupts.
-
-Example:
-
-	interrupt-controller@32e2d000 {
-		compatible = "fsl,imx8m-irqsteer", "fsl,imx-irqsteer";
-		reg = <0x32e2d000 0x1000>;
-		interrupts = <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clk IMX8MQ_CLK_DISP_APB_ROOT>;
-		clock-names = "ipg";
-		fsl,channel = <0>;
-		fsl,num-irqs = <64>;
-		interrupt-controller;
-		#interrupt-cells = <1>;
-	};
