1 Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface.
4 - compatible : "snps,dw-apb-ssi" or "mscc,<soc>-spi", where soc is "ocelot" or
5 "jaguar2", or "amazon,alpine-dw-apb-ssi"
6 - reg : The register base for the controller. For "mscc,<soc>-spi", a second
7 register set is required (named ICPU_CFG:SPI_MST)
8 - interrupts : One interrupt, used by the controller.
9 - #address-cells : <1>, as required by generic SPI binding.
10 - #size-cells : <0>, also as required by generic SPI binding.
13 - cs-gpios : Specifies the gpio pis to be used for chipselects.
14 - num-cs : The number of chipselects. If omitted, this will default to 4.
15 - reg-io-width : The I/O register width (in bytes) implemented by this
16 device. Supported values are 2 or 4 (the default).
18 Child nodes as per the generic SPI binding.
