1Binding for Qualcomm Atheros AR7xxx/AR9XXX MISC interrupt controller
2
3The MISC interrupt controller is a secondary controller for lower priority
4interrupt.
5
6Required Properties:
7- compatible: has to be "qca,<soctype>-cpu-intc", "qca,ar7100-misc-intc" or
8  "qca,<soctype>-cpu-intc", "qca,ar7240-misc-intc"
9- reg: Base address and size of the controllers memory area
10- interrupts: Interrupt specifier for the controllers interrupt.
11- interrupt-controller : Identifies the node as an interrupt controller
12- #interrupt-cells : Specifies the number of cells needed to encode interrupt
13		     source, should be 1
14
15Compatible fallback depends on the SoC. Use ar7100 for ar71xx and ar913x,
16use ar7240 for all other SoCs.

21Example:
22
23	interrupt-controller@18060010 {
24		compatible = "qca,ar9132-misc-intc", "qca,ar7100-misc-intc";
25		reg = <0x18060010 0x4>;
26
27		interrupt-parent = <&cpuintc>;
28		interrupts = <6>;
29
30		interrupt-controller;
31		#interrupt-cells = <1>;
32	};
33
34Another example:
35
36	interrupt-controller@18060010 {
37		compatible = "qca,ar9331-misc-intc", qca,ar7240-misc-intc";
38		reg = <0x18060010 0x4>;
39
40		interrupt-parent = <&cpuintc>;
41		interrupts = <6>;
42
43		interrupt-controller;
44		#interrupt-cells = <1>;
45	};
