1 * Atmel Extensible Direct Memory Access Controller (XDMAC)
3 * XDMA Controller
5 - compatible: Should be "atmel,sama5d4-dma" or "microchip,sam9x60-dma".
6 - reg: Should contain DMA registers location and length.
7 - interrupts: Should contain DMA interrupt.
8 - #dma-cells: Must be <1>, used to represent the number of integer cells in
10   - The 1st cell specifies the channel configuration register:
11     - bit 13: SIF, source interface identifier, used to get the memory
13     - bit 14: DIF, destination interface identifier, used to get the peripheral
15     - bit 30-24: PERID, peripheral identifier.
19 dma1: dma-controller@f0004000 {
20 	compatible = "atmel,sama5d4-dma";
23 	#dma-cells = <1>;
28 DMA clients connected to the Atmel XDMA controller must use the format
29 described in the dma.txt file, using a one-cell specifier for each channel.
31 1. A phandle pointing to the DMA controller.
33     - bit 13: SIF, source interface identifier, used to get the memory
35     - bit 14: DIF, destination interface identifier, used to get the peripheral
37   - bit 30-24: PERID, peripheral identifier.
