      2C-SKY Multi-processors Interrupt Controller
      3===========================================
      4
      5C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
      6SMP soc, and it also could be used in non-SMP system.
      7
      8Interrupt number definition:
      9  0-15  : software irq, and we use 15 as our IPI_IRQ.
     10 16-31  : private  irq, and we use 16 as the co-processor timer.
     11 31-1024: common irq for soc ip.
     12
     13Interrupt trigger mode: (Defined in dt-bindings/interrupt-controller/irq.h)
     14 IRQ_TYPE_LEVEL_HIGH (default)
     15 IRQ_TYPE_LEVEL_LOW
     16 IRQ_TYPE_EDGE_RISING
     17 IRQ_TYPE_EDGE_FALLING
