|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
Child nodes as per the generic SPI binding.

|
|
|
||
|
