+* Advanced Interrupt Controller (AIC)
+
+Required properties:
+- compatible: Should be "atmel,<chip>-aic"
+- interrupt-controller: Identifies the node as an interrupt controller.
+- interrupt-parent: For single AIC system, it is an empty property.
+- #interrupt-cells: The number of cells to define the interrupts. It sould be 2.
+  The first cell is the IRQ number (aka "Peripheral IDentifier" on datasheet).
+  The second cell is used to specify flags:
+    bits[3:0] trigger type and level flags:
+      1 = low-to-high edge triggered.
+      2 = high-to-low edge triggered.
+      4 = active high level-sensitive.
+      8 = active low level-sensitive.
+      Valid combinations are 1, 2, 3, 4, 8.
+      Default flag for internal sources should be set to 4 (active high).
+- reg: Should contain AIC registers location and length
+
+Examples:
+        /*
+         * AIC
+         */
+        aic: interrupt-controller@fffff000 {
+                compatible = "atmel,at91rm9200-aic";
+                interrupt-controller;

+                #interrupt-cells = <2>;
+                reg = <0xfffff000 0x200>;
+        };
+
+        /*
+         * An interrupt generating device that is wired to an AIC.
+         */
+        dma: dma-controller@ffffec00 {
+                compatible = "atmel,at91sam9g45-dma";
+                reg = <0xffffec00 0x200>;

+        };

+Atmel AT91 device tree bindings.
+================================
+
+PIT Timer required properties:
+- compatible: Should be "atmel,at91sam9260-pit"
+- reg: Should contain registers location and length
+- interrupts: Should contain interrupt for the PIT which is the IRQ line
+  shared across all System Controller members.
+
+TC/TCLIB Timer required properties:
+- compatible: Should be "atmel,<chip>-pit".
+  <chip> can be "at91rm9200" or "at91sam9x5"
+- reg: Should contain registers location and length
+- interrupts: Should contain all interrupts for the TC block
+  Note that you can specify several interrupt cells if the TC
+  block has one interrupt per channel.
+
+Examples:
+
+One interrupt per TC block:
+        tcb0: timer@fff7c000 {
+                compatible = "atmel,at91rm9200-tcb";
+                reg = <0xfff7c000 0x100>;
+                interrupts = <18 4>;
+        };
+
+One interrupt per TC channel in a TC block:
+        tcb1: timer@fffdc000 {
+                compatible = "atmel,at91rm9200-tcb";
+                reg = <0xfffdc000 0x100>;
+                interrupts = <26 4 27 4 28 4>;
+        };

+* Atmel GPIO controller (PIO)
+
+Required properties:
+- compatible: "atmel,<chip>-gpio", where <chip> is at91rm9200 or at91sam9x5.
+- reg: Should contain GPIO controller registers location and length
+- interrupts: Should be the port interrupt shared by all the pins.
+- #gpio-cells: Should be two.  The first cell is the pin number and
+  the second cell is used to specify optional parameters (currently
+  unused).
+- gpio-controller: Marks the device node as a GPIO controller.
