description:
  This interrupt controller is found in the Loongson LS7A family of PCH for
  accepting interrupts sent by LPC-connected peripherals and signalling PIC
  via a single interrupt line when interrupts are available.

  compatible:
    const: loongson,ls7a-lpc

  reg:
    maxItems: 1

  interrupt-controller: true

  interrupts:
    maxItems: 1
 
  '#interrupt-cells':
    const: 2

required:
  - compatible
  - reg
  - interrupt-controller
  - interrupts
