+   l) RapidIO
+
+   RapidIO is a definition of a system interconnect. This node add
+   the support for RapidIO processor in kernel. The node name is
+   suggested to be 'rapidio'.
+
+   Required properties:
+
+    - compatible : Using "fsl,rapidio-delta" for Freescale PowerPC
+      RapidIO controller.
+    - #address-cells : Address representation for "rapidio" devices.
+      This field represents the number of cells needed to represent
+      the RapidIO address of the registers.
+      See 1) above for more details on defining #address-cells.
+    - reg : Offset and length of the register set for the device
+    - ranges : Should be defined as specified in 1) to describe the
+      translation of addresses for memory mapped RapidIO memory
+      space.
+    - interrupts : binding interrupts for this device node,
+      please follow below orders:
+      <err_irq bell_outb_irq bell_inb_irq msg1_tx_irq msg1_rx_irq
+      msg2_tx_irq msg2_rx_irq ... msgN_tx_irq msgN_rx_irq>.
+
+  Example:
+
+	rapidio at c0000 {
+		compatible = "fsl,rapidio-delta";
+		#address-cells = <2>;
+		#size-cells = <2>;
+		reg = <c0000 20000>;
+		ranges = <0 0 c0000000 20000000>;
+		interrupt-parent = <&mpic>;
+		/* err_irq bell_outb_irq bell_inb_irq msg1_tx_irq msg1_rx_irq
+						      msg2_tx_irq msg2_rx_irq */
+		interrupts = <30 2 31 2 32 2 35 2 36 2 37 2 38 2>;
+	};
+
    More devices will be defined as this spec matures.
