[PATCH v3 0/1] Switchtec Switch DMA Engine Driver

[Kelvin Cao <kelvin.cao@microchip.com>]

Hi,

This is v3 of the Switchtec Switch DMA Engine Driver, incorporating
changes for the v2 review comments.

v3 changes:
  - Remove some unnecessary memory/variable zeroing

v2 changes:
  - Move put_device(dma_dev->dev) before kfree(swdma_dev) as dma_dev is
    part of swdma_dev.
  - Convert dev_ print calls to pci_ print calls to make the use of
    print functions consistent within switchtec_dma_create().
  - Remove some dev_ print calls, which use device pointer as handles,
    to ensure there's no reference issue when the device is unbound.
  - Remove unused .driver_data from pci_device_id structure.

v1:
The following patch implements a DMAEngine driver to use the DMA
controller in Switchtec PSX/PFX switchtes. The DMA controller appears as
a PCI function on the switch upstream port. The DMA function can include
one or more DMA channels.

This patchset is based off of v6.3-rc1.
