-* BCM2835 DMA controller
-
-The BCM2835 DMA controller has 16 channels in total.
-Only the lower 13 channels have an associated IRQ.
-Some arbitrary channels are used by the firmware
-(1,3,6,7 in the current firmware version).
-The channels 0,2 and 3 have special functionality
-and should not be used by the driver.
-
-Required properties:
-- compatible: Should be "brcm,bcm2835-dma".
-- reg: Should contain DMA registers location and length.
-- interrupts: Should contain the DMA interrupts associated
-		to the DMA channels in ascending order.
-- interrupt-names: Should contain the names of the interrupt
-		   in the form "dmaXX".
-		   Use "dma-shared-all" for the common interrupt line
-		   that is shared by all dma channels.
-- #dma-cells: Must be <1>, the cell in the dmas property of the
-		client device represents the DREQ number.
-- brcm,dma-channel-mask: Bit mask representing the channels
-			 not used by the firmware in ascending order,
-			 i.e. first channel corresponds to LSB.
