| Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface. |
| |
| Required properties: |
| - compatible : "snps,dw-apb-ssi" |
| - reg : The register base for the controller. |
| - interrupts : One interrupt, used by the controller. |
| - #address-cells : <1>, as required by generic SPI binding. |
| - #size-cells : <0>, also as required by generic SPI binding. |
| |
| Optional properties: |
| - cs-gpios : Specifies the gpio pis to be used for chipselects. |
| - num-cs : The number of chipselects. If omitted, this will default to 4. |
| - reg-io-width : The I/O register width (in bytes) implemented by this |
| device. Supported values are 2 or 4 (the default). |
| |
| Child nodes as per the generic SPI binding. |
| |
| Example: |
| |
| spi@fff00000 { |
| compatible = "snps,dw-apb-ssi"; |
| reg = <0xfff00000 0x1000>; |
| interrupts = <0 154 4>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| num-cs = <2>; |
| cs-gpios = <&gpio0 13 0>, |
| <&gpio0 14 0>; |
| }; |
