1 | Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface. |
2 | ||
3 | Required 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. | |

10 | Optional 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. | |
