Xilinx ZynqMP DMA engine, it does support memory to memory transfers,
|
memory to device and device to memory transfers. It also has flow
|
control and rate control support for slave/peripheral dma access.
|
|
Required properties:
|
- compatible : Should be "xlnx,zynqmp-dma-1.0"
|
- reg : Memory map for gdma/adma module access.
|
- interrupts : Should contain DMA channel interrupt.
|
- xlnx,bus-width : Axi buswidth in bits. Should contain 128 or 64
|
- clock-names : List of input clocks "clk_main", "clk_apb"
|
(see clock bindings for details)
|
|
Optional properties:
|
- dma-coherent : Present if dma operations are coherent.
|
|
Example:
|
++++++++
|
fpd_dma_chan1: dma@fd500000 {
|
compatible = "xlnx,zynqmp-dma-1.0";
|
reg = <0x0 0xFD500000 0x1000>;
|
interrupt-parent = <&gic>;
|
interrupts = <0 117 4>;
|
clock-names = "clk_main", "clk_apb";
|
xlnx,bus-width = <128>;
|
dma-coherent;
|
};
