+Binding for Qualcomm Atheros AR7xxx/AR9XXX MISC interrupt controller
+
+The MISC interrupt controller is a secondary controller for lower priority
+interrupt.
+
+Required Properties:
+- compatible: has to be "qca,<soctype>-cpu-intc", "qca,ar7100-misc-intc"
+ as fallback
+- reg: Base address and size of the controllers memory area
+- interrupt-parent: phandle of the parent interrupt controller.
+- interrupts: Interrupt specifier for the controllers interrupt.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode interrupt
+ source, should be 1
+
+Please refer to interrupts.txt in this directory for details of the common
+Interrupt Controllers bindings used by client devices.
+
+Example:
+
+ interrupt-controller@18060010 {
+ compatible = "qca,ar9132-misc-intc", qca,ar7100-misc-intc";
+ reg = <0x18060010 0x4>;
+
+ interrupt-parent = <&cpuintc>;
+ interrupts = <6>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ };
