+* 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>;
