1 * Atmel Extensible Direct Memory Access Controller (XDMAC)
5 - compatible: Should be "atmel,sama5d4-dma", "microchip,sam9x60-dma" or
6 "microchip,sama7g5-dma".
7 - reg: Should contain DMA registers location and length.
8 - interrupts: Should contain DMA interrupt.
9 - #dma-cells: Must be <1>, used to represent the number of integer cells in
10 the dmas property of client devices.
11 - The 1st cell specifies the channel configuration register:
12 - bit 13: SIF, source interface identifier, used to get the memory
14 - bit 14: DIF, destination interface identifier, used to get the peripheral
16 - bit 30-24: PERID, peripheral identifier.

23 interrupts = <50 4 0>;
29 DMA clients connected to the Atmel XDMA controller must use the format
30 described in the dma.txt file, using a one-cell specifier for each channel.
31 The two cells in order are:
32 1. A phandle pointing to the DMA controller.
33 2. Channel configuration register. Configurable fields are:
34 - bit 13: SIF, source interface identifier, used to get the memory
36 - bit 14: DIF, destination interface identifier, used to get the peripheral
38 - bit 30-24: PERID, peripheral identifier.
