   1 * Marvell MMP Interrupt controller
   2
   3 Required properties:
   4 - compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or
   5   "mrvl,mmp2-mux-intc"
   6 - reg : Address and length of the register set of the interrupt controller.
   7   If the interrupt controller is intc, address and length means the range
   8   of the whold interrupt controller. If the interrupt controller is mux-intc,
   9   address and length means one register. Since address of mux-intc is in the
  10   range of intc. mux-intc is secondary interrupt controller.
  11 - reg-names : Name of the register set of the interrupt controller. It's
  12   only required in mux-intc interrupt controller.
  13 - interrupts : Should be the port interrupt shared by mux interrupts. It's
  14   only required in mux-intc interrupt controller.
  15 - interrupt-controller : Identifies the node as an interrupt controller.
  16 - #interrupt-cells : Specifies the number of cells needed to encode an
  17   interrupt source.
  18 - mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
  19   controller.
  20 - mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
  21   detection first.
  22
  23 Example:
  24         intc: interrupt-controller@d4282000 {
  25                 compatible = "mrvl,mmp2-intc";
  26                 interrupt-controller;
  27                 #interrupt-cells = <1>;
  28                 reg = <0xd4282000 0x1000>;
  29                 mrvl,intc-nr-irqs = <64>;
  30         };
  31
  32         intcmux4@d4282150 {
  33                 compatible = "mrvl,mmp2-mux-intc";
  34                 interrupts = <4>;
  35                 interrupt-controller;
  36                 #interrupt-cells = <1>;
  37                 reg = <0x150 0x4>, <0x168 0x4>;
  38                 reg-names = "mux status", "mux mask";
  39                 mrvl,intc-nr-irqs = <2>;
  40         };
  41
  42 * Marvell Orion Interrupt controller
  43
  44 Required properties
  45 - compatible :  Should be "marvell,orion-intc".
  46 - #interrupt-cells: Specifies the number of cells needed to encode an
  47   interrupt source. Supported value is <1>.
  48 - interrupt-controller : Declare this node to be an interrupt controller.
  49 - reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
  50         One entry in the list represents 32 interrupts.
  51
  52 Example:
  53
  54         intc: interrupt-controller {
  55                 compatible = "marvell,orion-intc", "marvell,intc";
  56                 interrupt-controller;
  57                 #interrupt-cells = <1>;
  58                 reg = <0xfed20204 0x04>,
  59                       <0xfed20214 0x04>;
  60         };
