1 Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface.
4 - compatible : "snps,dw-apb-ssi"
5 - reg : The register base for the controller.
6 - interrupts : One interrupt, used by the controller.
7 - #address-cells : <1>, as required by generic SPI binding.
8 - #size-cells : <0>, also as required by generic SPI binding.
11 - cs-gpios : Specifies the gpio pis to be used for chipselects.
12 - num-cs : The number of chipselects. If omitted, this will default to 4.
13 - reg-io-width : The I/O register width (in bytes) implemented by this
14 device. Supported values are 2 or 4 (the default).
16 Child nodes as per the generic SPI binding.
