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 "fsl,ls1012a-dspi" followed by "fsl,ls1021a-v1.0-dspi"
9 "fsl,ls1088a-dspi" followed by "fsl,ls1021a-v1.0-dspi"
10 - reg : Offset and length of the register set for the device
11 - interrupts : Should contain SPI controller interrupt
12 - clocks: from common clock binding: handle to dspi clock.
13 - clock-names: from common clock binding: Shall be "dspi".
14 - pinctrl-0: pin control group to be used for this controller.
15 - pinctrl-names: must contain a "default" entry.
16 - spi-num-chipselects : the number of the chipselect signals.
17 - bus-num : the slave chip chipselect signal number.
20 - big-endian: If present the dspi device's registers are implemented
23 Optional SPI slave node properties:
24 - fsl,spi-cs-sck-delay: a delay in nanoseconds between activating chip
25 select and the start of clock signal, at the start of a transfer.
26 - fsl,spi-sck-cs-delay: a delay in nanoseconds between stopping the clock
27 signal and deactivating chip select, at the end of a transfer.
