1	Atmel SPI device
2	
3	Required properties:
4	- compatible : should be "atmel,at91rm9200-spi".
5	- reg: Address and length of the register set for the device
6	- interrupts: Should contain spi interrupt
7	- cs-gpios: chipselects
8	- clock-names: tuple listing input clock names.
9		Required elements: "spi_clk"
10	- clocks: phandles to input clocks.
11	
12	Example:
13	
14	spi1: spi@fffcc000 {
15		compatible = "atmel,at91rm9200-spi";

17		interrupts = <13 4 5>;
18		#address-cells = <1>;
19		#size-cells = <0>;
20		clocks = <&spi1_clk>;
