-* Freescale MXS DMA
-
-Required properties:
-- compatible : Should be "fsl,<chip>-dma-apbh" or "fsl,<chip>-dma-apbx"
-- reg : Should contain registers location and length
-- interrupts : Should contain the interrupt numbers of DMA channels.
-  If a channel is empty/reserved, 0 should be filled in place.
-- #dma-cells : Must be <1>.  The number cell specifies the channel ID.
-- dma-channels : Number of channels supported by the DMA controller
-
-Optional properties:
-- interrupt-names : Name of DMA channel interrupts
-
-Supported chips:
-imx23, imx28.
-
-Examples:
-
-dma_apbh: dma-apbh@80004000 {
-	compatible = "fsl,imx28-dma-apbh";

-DMA clients connected to the MXS DMA controller must use the format
-described in the dma.txt file.
-
-Examples:
-
