* Atmel SSC driver.
Required properties:
- compatible: "atmel,at91rm9200-ssc" or "atmel,at91sam9g45-ssc"
- atmel,at91rm9200-ssc: support pdc transfer
- atmel,at91sam9g45-ssc: support dma transfer
- reg: Should contain SSC registers location and length
- interrupts: Should contain SSC interrupt
Required properties for devices compatible with "atmel,at91sam9g45-ssc":
- dmas: DMA specifier, consisting of a phandle to DMA controller node,
the memory interface and SSC DMA channel ID (for tx and rx).
See Documentation/devicetree/bindings/dma/atmel-dma.txt for details.
- dma-names: Must be "tx", "rx".
Examples:
- PDC transfer:
ssc0: ssc@fffbc000 {
compatible = "atmel,at91rm9200-ssc";
reg = <0xfffbc000 0x4000>;
interrupts = <14 4 5>;
};
- DMA transfer:
ssc0: ssc@f0010000 {
compatible = "atmel,at91sam9g45-ssc";
reg = <0xf0010000 0x4000>;
interrupts = <28 4 5>;
dmas = <&dma0 1 13>,
<&dma0 1 14>;
dma-names = "tx", "rx";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ssc0_tx &pinctrl_ssc0_rx>;
status = "disabled";
};
