description: |+
  MStar, SigmaStar and Mediatek TV SoCs contain multiple legacy
  interrupt controllers that routes interrupts to the GIC.

  The HW block exposes a number of interrupt controllers, each
  can support up to 64 interrupts.

properties:
  compatible:
    const: mstar,mst-intc

  interrupt-controller: true

  "#interrupt-cells":
    const: 3
    description: |
      Use the same format as specified by GIC in arm,gic.yaml.

  reg:
    maxItems: 1

  mstar,irqs-map-range:
    description: |
      The range <start, end> of parent interrupt controller's interrupt
      lines that are hardwired to mstar interrupt controller.
    $ref: /schemas/types.yaml#/definitions/uint32-matrix
    items:
      minItems: 2
      maxItems: 2

  mstar,intc-no-eoi:
    description:
      Mark this controller has no End Of Interrupt(EOI) implementation.
    type: boolean

required:
  - compatible
  - reg
  - mstar,irqs-map-range
