* Freescale MX233/MX28 SSP/SPI

Required properties:
- compatible: Should be "fsl,<soc>-spi", where soc is "imx23" or "imx28"
- reg: Offset and length of the register set for the device
- 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 0x2000>;
	interrupts = <96 82>;
	fsl,ssp-dma-channel = <0>;
};
