+BCM2835 Auxiliary ("AUXIRQ") Interrupt Controller
+
+The BCM2835 family of SoCs multiplexes the interrupts for peripherals in
+the AUX block into a single IRQ. The AUXIRQ register shows the IRQ status
+of each of the peripherals. Note that there are no masking or clearing
+facilities - interrupts must be enabled and acknowledged in the
+individual peripherals.
+
+Required properties:
+- compatible :	     Should be "brcm,bcm2835-aux-intc".
+- reg :		     Specifies base physical address and size of the registers.
+- interrupts :	     The interrupt number - see
+		     bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+		     interrupt source. The value shall be 1.
+
+  The cell contains the interrupt specifier, as found in
+  include/dt-bindings/interrupt-controller/bcm2835-aux-intc.h.
+
+Example:
+
+	auxintc: interrupt-controller@7e215000 {
+		compatible = "brcm,bcm2835-aux-intc";
+		reg = <0x7e215000 0x4>;
+		interrupts = <1 29>;
+		interrupt-controller;
looks like the end of the file has been truncated and example misses some lines.
