* 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



Example:

ssc0: ssc@fffbc000 {

	compatible = "atmel,at91rm9200-ssc";

	reg = <0xfffbc000 0x4000>;

	interrupts = <14 4 5>;
