Should probably recommend a name for the node here, as well. "srio" I guess, from the example below.
+ - compatible : Should be "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. For supporting more than
+ 32-bits RapidIO address, this field should be <2>.
+ 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 sector,
+ 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:
+
+ srio@c0000{
+ compatible = "fsl,rapidio-delta";
+ #address-cells = <2>;
+ #size-cells = <2>;
+ reg = <c0000 20000>;

+ /* 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.
