3Required properties:
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.
9
10Optional properties:
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).
15
16Child nodes as per the generic SPI binding.
