1 ARM Freescale DSPI controller
4 - compatible : "fsl,vf610-dspi", "fsl,ls1021a-v1.0-dspi",
7 "fsl,ls2080a-dspi" followed by "fsl,ls2085a-dspi"
8 - reg : Offset and length of the register set for the device
9 - interrupts : Should contain SPI controller interrupt
10 - clocks: from common clock binding: handle to dspi clock.
11 - clock-names: from common clock binding: Shall be "dspi".
12 - pinctrl-0: pin control group to be used for this controller.
13 - pinctrl-names: must contain a "default" entry.
14 - spi-num-chipselects : the number of the chipselect signals.
15 - bus-num : the slave chip chipselect signal number.
18 - big-endian: If present the dspi device's registers are implemented
21 Optional SPI slave node properties:
22 - fsl,spi-cs-sck-delay: a delay in nanoseconds between activating chip
23 select and the start of clock signal, at the start of a transfer.
24 - fsl,spi-sck-cs-delay: a delay in nanoseconds between stopping the clock
25 signal and deactivating chip select, at the end of a transfer.
