I use this in 8313erdb.dts, but can not find DMA info in
/proc/interrupts.why?

dma@8030 { 
			#address-cells = <1>; 
			#size-cells = <1>; 
			compatible = "fsl,elo-dma"; 
			cell-index = <0>; 
			reg = <8030 2d0>; /* DMA general status register */ 
			ranges = <0 8100 200>; 

			dma-channel@0 { 
				compatible = "fsl,elo-dma-channel"; 
				cell-index = <0>; 
				reg = <0 80>; 
				interrupt-parent = <700>; 
				interrupts = <47 8>; 
			}; 
			dma-channel@1 { 
				compatible = "fsl,elo-dma-channel"; 
				cell-index = <1>; 
				reg = <80 80>; 
				interrupt-parent = <700>; 
				interrupts = <47 8>; 
			}; 
			dma-channel@2 { 
				compatible = "fsl,elo-dma-channel"; 
				cell-index = <2>; 
				reg = <100 80>; 
				interrupt-parent = <700>; 
				interrupts = <47 8>; 
			}; 
			dma-channel@3 { 
				compatible = "fsl,elo-dma-channel"; 
				cell-index = <3>; 
				reg = <180 80>; 
				interrupt-parent = <700>; 
				interrupts = <47 8>; 
			};
		}
