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.
