 FPGA type interrupt controllers, see the versatile-fpga-irq binding doc.
 
+Required nodes:
+
 In the root node the Integrator/CP must have a /cpcon node pointing
 to the CP control registers, and the Integrator/AP must have a
 /syscon node pointing to the Integrator/AP system controller.
+The AP syscon node must include the logic module interrupts, stated
+in order of module instance <module 0, module 1, module 2 ...>
+example:
