+* Interrupt Controllers
+
+Currently defined compatibles:
+- fsl,cpm1-pic
+  - only one interrupt cell
+- fsl,pq1-pic
+- fsl,cpm2-pic
+  - second interrupt cell is level/sense:
+    - 2 is falling edge
+    - 8 is active low
+
+Example:
+       interrupt-controller@10c00 {
+               #interrupt-cells = <2>;
+               interrupt-controller;
+               reg = <10c00 80>;
+               compatible = "mpc8272-pic", "fsl,cpm2-pic";
+       };
