+Atmel SPI device
+
+Required properties:
+- compatible : should be "atmel,at91rm9200-spi".
+- reg: Address and length of the register set for the device
+- interrupts: Should contain spi interrupt
+- cs-gpios: chipselects
+
+Example:
+
+spi1: spi@fffcc000 {
+ compatible = "atmel,at91rm9200-spi";
+ reg = <0xfffcc000 0x4000>;
+ interrupts = <13 4 5>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cs-gpios = <&pioB 3 0>;
+ status = "okay";
+
+ mmc-slot@0 {
+ compatible = "mmc-spi-slot";
+ reg = <0>;
+ gpios = <&pioC 4 0>; /* CD */
+ spi-max-frequency = <25000000>;
+ };
+};
