1 * BCM2835 DMA controller
3 The BCM2835 DMA controller has 16 channels in total.
5 Some arbitrary channels are used by the firmware
6 (1,3,6,7 in the current firmware version).
11 - compatible: Should be "brcm,bcm2835-dma".
12 - reg: Should contain DMA registers location and length.
13 - interrupts: Should contain the DMA interrupts associated
15 - interrupt-names: Should contain the names of the interrupt
17 		   Use "dma-shared-all" for the common interrupt line
19 - #dma-cells: Must be <1>, the cell in the dmas property of the
21 - brcm,dma-channel-mask: Bit mask representing the channels
22 			 not used by the firmware in ascending order,
28 	compatible = "brcm,bcm2835-dma";

48 	interrupt-names = "dma0",
63 			  "dma-shared-all";
65 	#dma-cells = <1>;
66 	brcm,dma-channel-mask = <0x7f35>;
70 DMA clients connected to the BCM2835 DMA controller must use the format
71 described in the dma.txt file, using a two-cell specifier for each channel.
