Linux device-tree for Zynq 70xx PL330 DMAC

Hi.

 

I'm trying to use the Zynq's on-chip PL330 DMA controller, along with a Peripheral Request Interface (PRI) to read from an AXI FIFO. Does anyone know how to construct the FIFO description for the DMAC device-tree node?

I'm using kernel version 4.4, so the document at http://www.wiki.xilinx.com/Zynq+Linux+pl330+DMA is not pertinent.

Thanks,
 
-Nick
