[PATCH v3 0/3] PLX Switch DMA Engine Driver

[Logan Gunthorpe]

This is v3 of the patchset. The in-use unbind bits have been sent and
accepted as a separate patch set. This patchset just includes the new
driver which has been updated to use the common reference counting.

This patchset is based off of vkoul/slave-dma.git/next and a git branch is
available here:

https://github.com/sbates130272/linux-p2pmem/ plx-dma-v3

Changes for v3:
* Common in-use unbind bits were submitted as a separate patch set
* Rebased onto vkoul/slave-dma.git/next (as of Jan 3rd 2020)

Changes for v2:

* Rebased onto v5.5-rc1 (no changes)
* Pushed the plx_dma_isr() routine into the patch that uses it (per
  Vinod's feedback)

  dmaengine: plx-dma: Introduce PLX DMA engine PCI driver skeleton
  dmaengine: plx-dma: Implement hardware initialization and cleanup
  dmaengine: plx-dma: Implement descriptor submission
