1 Allwinner Sunxi Interrupt Controller
5 - compatible : should be "allwinner,sun4i-ic"
6 - reg : Specifies base physical address and size of the registers.
7 - interrupt-controller : Identifies the node as an interrupt controller
8 - #interrupt-cells : Specifies the number of cells needed to encode an
9 interrupt source. The value shall be 1.
11 The interrupt sources are as follows:
99 intc: interrupt-controller {
100 compatible = "allwinner,sun4i-ic";
101 reg = <0x01c20400 0x400>;
102 interrupt-controller;
103 #interrupt-cells = <2>;
