1 Applied Micro X-Gene SoC DMA nodes
3 DMA nodes are defined to describe on-chip DMA interfaces in
4 APM X-Gene SoC.
6 Required properties for DMA interfaces:
7 - compatible: Should be "apm,xgene-dma".
8 - device_type: set to "dma".
9 - reg: Address and length of the register set for the device.
11 1st - DMA control and status register address space.
12 2nd - Descriptor ring control and status register address space.
13 3rd - Descriptor ring command register address space.
14 4th - Soc efuse register address space.
15 - interrupts: DMA has 5 interrupts sources. 1st interrupt is
16 DMA error reporting interrupt. 2nd, 3rd, 4th and 5th interrupts
17 are completion interrupts for each DMA channels.
18 - clocks: Reference to the clock entry.
21 - dma-coherent : Present if dma operations are coherent
