|
|
Required properties:
|
- compatible: Should be "fsl,<soc>-spi", where soc is "imx23" or "imx28"
|
- reg: Offset and length of the register set for the device
|
- interrupts: Should contain SSP ERROR interrupt
|
- dmas: DMA specifier, consisting of a phandle to DMA controller node

Example:
|
|
ssp0: ssp@80010000 {
|
#address-cells = <1>;
|
#size-cells = <0>;
|
compatible = "fsl,imx28-spi";
|
reg = <0x80010000 0x2000>;
|
interrupts = <96>;
|
dmas = <&dma_apbh 0>;
|
dma-names = "rx-tx";
