Conexant Digicolor Interrupt Controller

Required properties:

• compatible : should be “cnxt,cx92755-ic”
• reg : Specifies base physical address and size of the interrupt controller
  registers (IC) area
• interrupt-controller : Identifies the node as an interrupt controller
• #interrupt-cells : Specifies the number of cells needed to encode an
  interrupt source. The value shall be 1.
• syscon: A phandle to the syscon node describing UC registers

Example:

intc: interrupt-controller@f0000040 {
    compatible = "cnxt,cx92755-ic";
    interrupt-controller;
    #interrupt-cells = <1>;
    reg = <0xf0000040 0x40>;
    syscon = <&uc_regs>;
};
