Rob Herring (Arm) 76f75212f8 dt-bindings: interrupt-controller: Convert snps,archs-idu-intc to DT schema
Convert the ARC-HS Interrupt Distribution Unit interrupt controller
binding to schema format. It's a straight-forward conversion of the
typical interrupt controller.

description: >
ARC-HS Interrupt Distribution Unit is an optional 2nd level interrupt
controller which can be used in SMP configurations for dynamic IRQ routing,
load balancing of common/external IRQs towards core intc.
The interrupt controller is accessed via the special ARC AUX register
interface, hence "reg" property is not specified.
properties:
compatible:
const: snps,archs-idu-intc
interrupt-controller: true
'#interrupt-cells':
description: |
Number of interrupt specifier cells:
- 1: only a common IRQ is specified.
- 2: a second cell encodes trigger type and level flags:
1 = low-to-high edge triggered
4 = active high level-sensitive (default)
enum: [1, 2]
required:
- compatible
- interrupt-controller
- '#interrupt-cells'
additionalProperties: false
examples:
- |
interrupt-controller {
compatible = "snps,archs-idu-intc";
interrupt-controller;
#interrupt-cells = <1>;
};
