+Interrupt chips
+---------------
+
+* Intel I/O Advanced Programmable Interrupt Controller (IO APIC)

+ Required properties:
+ --------------------
+ compatible = "intel,ce4100-ioapic";
+ #interrupt-cells = <2>;
+
+ Device's interrupt property:
+
+ interrupts = <P S>;
+
+ The first number (P) represents the interrupt pin which is wired to the
+ IO APIC. The second number (S) represents the sense of interrupt which
+ should be configured and can be one of:
+ 0 - Edge Rising
+ 1 - Level Low
+ 2 - Level High
+ 3 - Edge Falling
+
+* Local APIC
+ Required property:
