1ARM Freescale DSPI controller
2
3Required properties:
4- compatible : "fsl,vf610-dspi"
5- reg : Offset and length of the register set for the device
6- interrupts : Should contain SPI controller interrupt
7- clocks: from common clock binding: handle to dspi clock.
8- clock-names: from common clock binding: Shall be "dspi".
9- pinctrl-0: pin control group to be used for this controller.
10- pinctrl-names: must contain a "default" entry.
11- spi-num-chipselects : the number of the chipselect signals.
12- bus-num : the slave chip chipselect signal number.
