Freescale IRQSTEER Interrupt multiplexerRequired properties:- compatible: should be: - "fsl,imx8m-irqsteer" - "fsl,imx-irqsteer"- reg: Physical base address and size of registers.- interrupts: Should contain the parent interrupt line used to multiplex the input interrupts.- 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,irq-groups: Number of IRQ groups managed by this controller instance. Each group manages 64 input 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,irq-groups = <1>; interrupt-controller; #interrupt-cells = <1>; };
