1 Freescale IRQSTEER Interrupt multiplexer
2
3 Required 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 parent interrupt line used to multiplex the
10   input interrupts.
11 - clocks: Should contain one clock for entry in clock-names
12   see Documentation/devicetree/bindings/clock/clock-bindings.txt
13 - clock-names:
14    - "ipg": main logic clock
15 - interrupt-controller: Identifies the node as an interrupt controller.
16 - #interrupt-cells: Specifies the number of cells needed to encode an
17   interrupt source. The value must be 1.
18 - fsl,channel: The output channel that all input IRQs should be steered into.
19 - fsl,irq-groups: Number of IRQ groups managed by this controller instance.
20   Each group manages 64 input interrupts.
