1 ARM Freescale DSPI controller
4 - compatible : must be one of:
6 "fsl,ls1021a-v1.0-dspi",
7 "fsl,ls1012a-dspi" (optionally followed by "fsl,ls1021a-v1.0-dspi"),
9 "fsl,ls1043a-dspi" (optionally followed by "fsl,ls1021a-v1.0-dspi"),
10 "fsl,ls1046a-dspi" (optionally followed by "fsl,ls1021a-v1.0-dspi"),
11 "fsl,ls1088a-dspi" (optionally followed by "fsl,ls1021a-v1.0-dspi"),
12 "fsl,ls2080a-dspi" (optionally followed by "fsl,ls2085a-dspi"),
15 - reg : Offset and length of the register set for the device
16 - interrupts : Should contain SPI controller interrupt
17 - clocks: from common clock binding: handle to dspi clock.
18 - clock-names: from common clock binding: Shall be "dspi".
19 - pinctrl-0: pin control group to be used for this controller.
20 - pinctrl-names: must contain a "default" entry.
21 - spi-num-chipselects : the number of the chipselect signals.
24 - big-endian: If present the dspi device's registers are implemented
26 - bus-num : the slave chip chipselect signal number.
28 Optional SPI slave node properties:
29 - fsl,spi-cs-sck-delay: a delay in nanoseconds between activating chip
30 select and the start of clock signal, at the start of a transfer.
31 - fsl,spi-sck-cs-delay: a delay in nanoseconds between stopping the clock
32 signal and deactivating chip select, at the end of a transfer.
