1 * Freescale (Enhanced) Configurable Serial Peripheral Interface
5 - compatible : Should be "fsl,<soc>-cspi" or "fsl,<soc>-ecspi"
6 - reg : Offset and length of the register set for the device
7 - interrupts : Should contain CSPI/eCSPI interrupt
8 - fsl,spi-num-chipselects : Contains the number of the chipselect
9 - cs-gpios : Specifies the gpio pins to be used for chipselects.
10 - dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
11 Documentation/devicetree/bindings/dma/dma.txt
12 - dma-names: DMA request names should include "tx" and "rx" if present.
