description:
  The AST2400 and AST2500 SoC families include a legacy register layout before
  a redesigned layout, but the bindings do not prescribe the use of one or the
  other.

properties:
  compatible:
    enum:
      - aspeed,ast2400-vic
      - aspeed,ast2500-vic

  reg:
    maxItems: 1

  interrupt-controller: true

  "#interrupt-cells":
    const: 1
    description:
      Specifies the number of cells needed to encode an interrupt source. It
      must be 1 as the VIC has no configuration options for interrupt sources.
      The single cell defines the interrupt number.

      A bitmap of supported sources for the implementation.
