removing axi-dmac in the zynqmp-zcu102-rev10-adrv9009.dts

I would like to remove the DMA in the  zcu102-adrv9009 design. I have rebuild my hdf files without the axi-dmac.  I have replaced the DMA with a simple loopback.

I have following file which I need to edit zynqmp-zcu102-rev10-adrv9009.dts.

If I remove following part:

		rx_dma: dma@9c400000 {
			compatible = "adi,axi-dmac-1.00.a";
			reg = <0x9c400000 0x10000>;
			#dma-cells = <1>;
			#clock-cells = <0>;
			interrupts = <0 109 0>;
			clocks = <&clk 73>;

			adi,channels {
				#size-cells = <0>;
				#address-cells = <1>;

				dma-channel@0 {
					reg = <0>;
					adi,source-bus-width = <64>;
					adi,source-bus-type = <2>;
					adi,destination-bus-width = <64>;
					adi,destination-bus-type = <0>;
				};
			};
		};

Then I have an  invalid dtb file, I need to remove the follow part as well. Due to the reference to the "dmas" and the "dma-names"

axi_adrv9009_core_rx: axi-adrv9009-rx-hpc@84a00000 {
			compatible = "adi,axi-adrv9009-rx-1.0";
			reg = <0x84a00000 0x8000>;
			dmas = <&rx_dma 0>;
			dma-names = "rx";
			spibus-connected = <&trx0_adrv9009>;
		};

But I need this part to enable the data input of the axi_adrv9009_core. And have the option to select the DDS mode

Pleas advise to solve this issue.

Thanks!
