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

Just to clarify - what I want to do is have the DMA servicing the UART whiled the driver transmits data throught the DMA with write() and reads from the DMA RXD buffer with read().
