+Required properties:
+- compatible: Should be "fsl,<soc>-spi", where soc is "imx23" or "imx28"

+- interrupts: Should contain SSP interrupts (error irq first, dma irq second)
+- fsl,ssp-dma-channel: APBX DMA channel for the SSP
+
+Example:
+
+ssp0: ssp@80010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-spi";
+ reg = <0x80010000 2000>;
+ interrupts = <96 82>;
+ fsl,ssp-dma-channel = <0>;
