-* Freescale 83xx DMA Controller
-
-Freescale PowerPC 83xx have on chip general purpose DMA controllers.
-
-Required properties:
-
-- compatible        : compatible list, contains 2 entries, first is
-                "fsl,CHIP-dma", where CHIP is the processor
-                (mpc8349, mpc8360, etc.) and the second is
-                "fsl,elo-dma"
-- reg               : <registers mapping for DMA general status reg>
-- ranges               : Should be defined as specified in 1) to describe the
-                 DMA controller channels.
-- cell-index        : controller index.  0 for controller @ 0x8100
-- interrupts        : <interrupt mapping for DMA IRQ>
-- interrupt-parent  : optional, if needed for interrupt mapping
-
-
-- DMA channel nodes:
-        - compatible        : compatible list, contains 2 entries, first is
-                        "fsl,CHIP-dma-channel", where CHIP is the processor
-                        (mpc8349, mpc8350, etc.) and the second is
-                        "fsl,elo-dma-channel". However, see note below.
-        - reg               : <registers mapping for channel>
-        - cell-index        : dma channel index starts at 0.
-
-Optional properties:
-        - interrupts        : <interrupt mapping for DMA channel IRQ>
-                         (on 83xx this is expected to be identical to
-                          the interrupts property of the parent node)
-        - interrupt-parent  : optional, if needed for interrupt mapping
-
-Example:
-       dma@82a8 {

-Note on DMA channel compatible properties: The compatible property must say
-"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel" to be used by the Elo DMA
-driver (fsldma).  Any DMA channel used by fsldma cannot be used by another
-DMA driver, such as the SSI sound drivers for the MPC8610.  Therefore, any DMA
-channel that should be used for another driver should not use
-"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel".  For the SSI drivers, for
-example, the compatible property should be "fsl,ssi-dma-channel".  See ssi.txt
-for more information.
