change in v2:
	- Remove indentation
	- Add "Should be" before 'fsl,ls1021a-qdma'
	- Replace 'channels' by 'dma-channels'
	- Replace 'qdma@8390000' by 'dma-controller@8390000'

+* NXP Layerscape queue Direct Memory Access Controller(qDMA) Controller
+
+The qDMA controller transfers blocks of data between one source and one or more
+destinations. The blocks of data transferred can be represented in memory as contiguous
+or non-contiguous using scatter/gather table(s). Channel virtualization is supported
+through enqueuing of DMA jobs to, or dequeuing DMA jobs from, different work
+queues.
+
+* qDMA Controller
+Required properties:
+- compatible : Should be "fsl,ls1021a-qdma" or "fsl,ls1043a-qdma", "fsl,ls1021a-qdma"
+- reg : Specifies base physical address(s) and size of the qDMA registers.
+	The region is qDMA control register's address and size.
+- interrupts : A list of interrupt-specifiers, one for each entry in
+	interrupt-names.
+- interrupt-names : Should contain:
+	"qdma-error" - the error interrupt
+	"qdma-queue" - the queue interrupt
+- dma-channels : Number of DMA channels supported by the controller
+- queues : Number of queues supported by driver
+
+Optional properties:
+- big-endian: If present registers and hardware scatter/gather descriptors
+	of the qDMA are implemented in big endian mode, otherwise in little
+	mode.
+
+
+Examples:
+
+	qdma: dma-controller@8390000 {
+		compatible = "fsl,ls1021a-qdma";
+		reg = <0x0 0x8398000 0x0 0x2000 /* Controller registers */
+		       0x0 0x839a000 0x0 0x2000>; /* Block registers */
+		interrupts = <GIC_SPI 185 IRQ_TYPE_LEVEL_HIGH>,
+				<GIC_SPI 76 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-names = "qdma-error", "qdma-queue";
+		dma-channels = <8>;
+		queues = <2>;
+		big-endian;
+	};
