description: >
  C-SKY APB Interrupt Controller is a simple soc interrupt controller on the apb
  bus and we only use it as root irq controller.

    - csky,apb-intc is used in a lot of csky fpgas and socs, it support 64 irq nums.
    - csky,dual-apb-intc consists of 2 apb-intc and 128 irq nums supported.
    - csky,gx6605s-intc is gx6605s soc internal irq interrupt controller, 64 irq nums.

properties:
  compatible:
    enum:
      - csky,apb-intc
      - csky,dual-apb-intc
      - csky,gx6605s-intc

  reg:
    maxItems: 1

  '#interrupt-cells':
    const: 1

  interrupt-controller: true

  csky,support-pulse-signal:
    type: boolean
    description: Support for pulse signal flag.

additionalProperties: false

required:
