Software: Look at nios ii software developer's handbook (10.0) page 6-25 following. It's not exactly a tutorial but it's an example on how to use the DMA with HAL-driver.

I prefer to write the registers of the DMA directly without using the HAL. The functionality of the various registers and bits are described in the user guide mentioned above by Cris. See dma controller core -> software programming model -> register map.
