4Required properties:
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.
