UART connected to DMA with char HAL API

I am connecting the NIOS II UART to a DMA controller. Is it possible to use the standard HAL character mode API to open, read and write the /dev/uart. Thanks in advance, Joe

Thanks for all your feedback. I agree with the issues that you have pointed out. I had a problem with dropped RXD. I came across the FIFO'ed UART which addresses the problem nicely. So, goodbye UART-DMA union ;-)
