-NXP Layerscape SoC qDMA Controller
-==================================
-
-This device follows the generic DMA bindings defined in dma/dma.txt.
-
-Required properties:
-
-- compatible: Must be one of
- "fsl,ls1021a-qdma": for LS1021A Board
- "fsl,ls1028a-qdma": for LS1028A Board
- "fsl,ls1043a-qdma": for ls1043A Board
- "fsl,ls1046a-qdma": for ls1046A Board
-- reg: Should contain the register's base address and length.
-- interrupts: Should contain a reference to the interrupt used by this
- device.
-- interrupt-names: Should contain interrupt names:
- "qdma-queue0": the block0 interrupt
- "qdma-queue1": the block1 interrupt
- "qdma-queue2": the block2 interrupt
- "qdma-queue3": the block3 interrupt
- "qdma-error": the error interrupt
-- fsl,dma-queues: Should contain number of queues supported.
-- dma-channels: Number of DMA channels supported
-- block-number: the virtual block number
-- block-offset: the offset of different virtual block
-- status-sizes: status queue size of per virtual block
-- queue-sizes: command queue size of per virtual block, the size number
- based on queues
-
-Optional properties:
-
-- dma-channels: Number of DMA channels supported by the controller.
-- 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 0x8388000 0x0 0x1000>, /* Controller regs */
- <0x0 0x8389000 0x0 0x1000>, /* Status regs */
- <0x0 0x838a000 0x0 0x2000>; /* Block regs */
- interrupts = <GIC_SPI 185 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 76 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 77 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "qdma-error",
- "qdma-queue0", "qdma-queue1";
- dma-channels = <8>;
- block-number = <2>;
- block-offset = <0x1000>;
- fsl,dma-queues = <2>;
- status-sizes = <64>;
- queue-sizes = <64 64>;
- big-endian;
- };
-
-DMA clients must use the format described in dma/dma.txt file.

Convert binding doc from txt to yaml. Re-order interrupt-names to align example. Add #dma-cell in example. Change 'reg' in example to 32bit address.
