+==============================
+C-SKY APB Interrupt Controller
+==============================
+
+C-SKY APB Interrupt Controller is a simple soc interrupt controller
+on the apb bus and we only use it as root irq controller.
+
+ - csky,apb-intc is used in a lot of csky fpgas and socs, it support 64 irq nums.
+ - csky,dual-apb-intc consists of 2 apb-intc and 128 irq nums supported.
+ - csky,gx6605s-intc is gx6605s soc internal irq interrupt controller, 64 irq nums.
+
+=============================
+intc node bindings definition
+=============================
+
+ Description: Describes APB interrupt controller
+
+ PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: must be "csky,apb-intc"
+ "csky,dual-apb-intc"
+ "csky,gx6605s-intc"
+ - #interrupt-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be <1>
+ - reg
+ Usage: required
+ Value type: <u32 u32>
+ Definition: <phyaddr size> in soc from cpu view
+ - interrupt-controller:
+ Usage: required
+ - csky,support-pulse-signal:
+ Usage: select
+ Description: to support pulse signal flag
+
+Examples:
+---------
+
+ intc: interrupt-controller@500000 {
+ compatible = "csky,apb-intc";
+ #interrupt-cells = <1>;
+ reg = <0x00500000 0x400>;
+ interrupt-controller;
+ };
+
+ intc: interrupt-controller@500000 {
+ compatible = "csky,dual-apb-intc";
+ #interrupt-cells = <1>;
+ reg = <0x00500000 0x400>;
+ interrupt-controller;
+ };
+
+ intc: interrupt-controller@500000 {

+ #interrupt-cells = <1>;
+ reg = <0x00500000 0x400>;
