1 * Freescale MX233/MX28 SSP/SPI
4 - compatible: Should be "fsl,<soc>-spi", where soc is "imx23" or "imx28"
5 - reg: Offset and length of the register set for the device
6 - interrupts: Should contain SSP interrupts (error irq first, dma irq second)
7 - fsl,ssp-dma-channel: APBX DMA channel for the SSP
10 - clock-frequency : Input clock frequency to the SPI block in Hz.
11 Default is 160000000 Hz.
