Subject: [PATCH v4 fpga 0/4] Gather DMA for Zynq FPGA programming

Hi Greg/Alan,

This should be ready to land in 4.11, it is now fully acked.

The purpose of this series is to implement Gather DMA for Zynq FPGA
programming. Previously the driver would allocate a large contiguous DMA
buffer and copy the bitfile into it.

Jason Gunthorpe (4):
  fpga zynq: Check for errors after completing DMA
  fpga zynq: Check the bitstream for validity
  fpga: Add scatterlist based programming
  fpga zynq: Use the scatterlist interface
