1 * Atmel Extensible Direct Memory Access Controller (XDMAC)
3 * XDMA Controller
5 - compatible: Should be "atmel,sama5d4-dma", "microchip,sam9x60-dma" or
6   "microchip,sama7g5-dma" or
7   "microchip,sam9x7-dma", "atmel,sama5d4-dma".
8 - reg: Should contain DMA registers location and length.
9 - interrupts: Should contain DMA interrupt.
10 - #dma-cells: Must be <1>, used to represent the number of integer cells in
12   - The 1st cell specifies the channel configuration register:
13     - bit 13: SIF, source interface identifier, used to get the memory
15     - bit 14: DIF, destination interface identifier, used to get the peripheral
17     - bit 30-24: PERID, peripheral identifier.

29 * DMA clients
30 DMA clients connected to the Atmel XDMA controller must use the format
31 described in the dma.txt file, using a one-cell specifier for each channel.
33 1. A phandle pointing to the DMA controller.
35     - bit 13: SIF, source interface identifier, used to get the memory
37     - bit 14: DIF, destination interface identifier, used to get the peripheral
39   - bit 30-24: PERID, peripheral identifier.
