If you look at linux-next tree these UART dma channels are already been passed via the new 'dmas' method: auart1: serial@8006c000 { compatible = "fsl,imx28-auart", "fsl,imx23-auart"; reg = <0x8006c000 0x2000>; interrupts = <113 72 73>; dmas = <&dma_apbx 10>, <&dma_apbx 11>; dma-names = "rx", "tx"; clocks = <&clks 45>; status = "disabled"; };
