-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@...2d000 {
- 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>;
- };
