+===========================================
+C-SKY Multi-processors Interrupt Controller
+===========================================
+
+C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
+SMP soc, and it also could be used in non-SMP system.
+
+Interrupt number definition:
+
+ 0-15 : software irq, and we use 15 as our IPI_IRQ.
+ 16-31 : private irq, and we use 16 as the co-processor timer.
+ 31-1024: common irq for soc ip.
+
+=============================
+intc node bindings definition
+=============================
+
+ Description: Describes SMP interrupt controller
+
+ PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: must be "csky,mpintc"
+ - #interrupt-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be <1>
+ - interrupt-controller:
+ Usage: required
+
+Examples:
+---------
+
+ intc: interrupt-controller {
+ compatible = "csky,mpintc";
+ #interrupt-cells = <1>;
+ interrupt-controller;
+ };
