1* Freescale MXS DMA
2
3Required properties:
4- compatible : Should be "fsl,<chip>-dma-apbh" or "fsl,<chip>-dma-apbx"
5- reg : Should contain registers location and length
6- interrupts : Should contain the interrupt numbers of DMA channels.
7  If a channel is empty/reserved, 0 should be filled in place.
8- #dma-cells : Must be <1>.  The number cell specifies the channel ID.
9- dma-channels : Number of channels supported by the DMA controller
10
11Optional properties:
12- interrupt-names : Name of DMA channel interrupts
13
14Supported chips:
15imx23, imx28.
