| 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. |
| 9 | |
| 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. |
| Michael van der Westhuizen | 4b226fb | 2015-08-18 22:21:52 +0200 | [diff] [blame] | 13 | - reg-io-width : The I/O register width (in bytes) implemented by this |
| 14 | device. Supported values are 2 or 4 (the default). |
