1 ARM Freescale DSPI controller
4 - compatible : "fsl,vf610-dspi", "fsl,ls1021a-v1.0-dspi", "fsl,ls2085a-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.
15 - big-endian: If present the dspi device's registers are implemented
16 in big endian mode, otherwise in native mode(same with CPU), for more
17 detail please see: Documentation/devicetree/bindings/regmap/regmap.txt.
19 Optional SPI slave node properties:
20 - fsl,spi-cs-sck-delay: a delay in nanoseconds between activating chip
21 select and the start of clock signal, at the start of a transfer.
22 - fsl,spi-sck-cs-delay: a delay in nanoseconds between stopping the clock
23 signal and deactivating chip select, at the end of a transfer.
