1Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface. 2 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. 17 18Example: 19 20 spi@fff00000 { 21 compatible = "snps,dw-apb-ssi"; 22 reg = <0xfff00000 0x1000>; 23 interrupts = <0 154 4>; 24 #address-cells = <1>; 25 #size-cells = <0>; 26 num-cs = <2>; 27 cs-gpios = <&gpio0 13 0>, 28 <&gpio0 14 0>; 29 }; 30 31
