| 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. |
| - interrupt-parent : Interrupt controller the interrupt is routed through |
| - 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; |
| }; |
