     1 Sigma Designs SMP86xx/SMP87xx secondary interrupt controller
    2 
    3 Required properties:
    4 - compatible: should be "sigma,smp8642-intc"
    5 - reg: physical address of MMIO region
    6 - ranges: address space mapping of child nodes
    7 - interrupt-controller: boolean
    8 - #address-cells: should be <1>
    9 - #size-cells: should be <1>
   10 
   11 One child node per control block with properties:
   12 - reg: address of registers for this control block
   13 - interrupt-controller: boolean
   14 - #interrupt-cells: should be <2>, interrupt index and flags per interrupts.txt
   15 - interrupts: interrupt spec of primary interrupt controller
   16 
   17 Example:
   18 
   19 interrupt-controller@6e000 {
   20         compatible = "sigma,smp8642-intc";
   21         reg = <0x6e000 0x400>;
   22         ranges = <0x0 0x6e000 0x400>;
   23         interrupt-parent = <&gic>;
   24         interrupt-controller;
   25         #address-cells = <1>;
   26         #size-cells = <1>;
   27 
   28         irq0: interrupt-controller@0 {
   29                 reg = <0x000 0x100>;
   30                 interrupt-controller;
   31                 #interrupt-cells = <2>;
   32                 interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
   33         };
   34 
   35         irq1: interrupt-controller@100 {
   36                 reg = <0x100 0x100>;
   37                 interrupt-controller;
   38                 #interrupt-cells = <2>;
   39                 interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
   40         };
   41 
   42         irq2: interrupt-controller@300 {
   43                 reg = <0x300 0x100>;
   44                 interrupt-controller;
   45                 #interrupt-cells = <2>;
   46                 interrupts = <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>;
   47         };
   48 };
