Hi,
I am trying to use the async transfers with usarts, but it fails to enable the UART (using uart_rx_enable), due to no DMA configured for the usart.
I have not been able to modify the device tree for DMA, but so far unsuccessful.
On the dma2 node, I have changed the status from "disabled" to "okay", and modified the usart3 to reference the dma2 in "dmas".

Hello @sbend,
Could you please share the DMA controller node code, to check #DMA-cells
The phandle is pointing to the DMA controller node where the warning is related to cell 3
PS: uncomment dma-names, it's a required property
