+* Atmel ClassD driver under ALSA SoC architecture
+
+Required properties:
+- compatible
+ Should be "atmel,sama5d2-classd".
+- reg
+ Should contain ClassD registers location and length.
+- interrupts
+ Should contain the IRQ line for the ClassD.
+- dmas
+ One DMA specifiers as described in atmel-dma.txt and dma.txt files.
+- dma-names
+ Must be "tx".
+- clock-names
+ Tuple listing input clock names.
+ Required elements: "pclk", "gclk" and "aclk".
+- clocks
+ Please refer to clock-bindings.txt.
