This patchset adds a dmadev driver and associated documentation to support
Intel QuickData Technology devices, part of the Intel I/O Acceleration
Technology (Intel I/OAT). This driver is intended to ultimately replace
the current IOAT part of the IOAT rawdev driver.
This patchset passes all the driver tests added in the dmadev test suite.

Depends-on: series-19737 ("add dmadev driver for idxd devices")

---

v8:
 - Fixed compliation issue for individual patches.
 - Rebased on main and v8 of IDXD.

v7:
 - Minor rework to update from v23 to v26 of the dmadev lib.

v6:
 - Added rawdev IOAT deprecation notice to deprecation.rst.

v5:
 - Updated to v23 of the dmadev lib.
 - Removed experimental tag for driver from MAINTAINERS.
 - Seperated IOAT and IDXD announcements in release notes.
 - Added missing check for rte_dma_get_dev_id in destroy.
 - Fixed memleak in destroy caused by NULL pointer.
 - Rewrote part of the docs to reduce duplication with DMA and IDXD.
 - Added patch to deprecate the rawdev IOAT driver.
 - Reworked destroy and close functions.
 - Added RTE_DMA_CAPA_HANDLES_ERRORS flag for IOAT versions >=3.4.
 - Other minor changes to IOAT driver.

v4:
 - Changes needed to update from dmadev v21 to v22.
 - Fixed 32-bit build.
 - Made stats reset logic easier to understand.

v3:
 - Added burst capacity function.
 - Stop function now waits for suspend rather than just using a sleep.
 - Changed from vchan idle to vchan status function.
 - Other minor changes to update from dmadev v19 to v21.

v2:
 - Rebased on the above patchsets.

Conor Walsh (12):
  dma/ioat: add device probe and removal functions
  dma/ioat: create dmadev instances on PCI probe
  dma/ioat: add datapath structures
  dma/ioat: add configuration functions
  dma/ioat: add start and stop functions
  dma/ioat: add data path job submission functions
  dma/ioat: add data path completion functions
  dma/ioat: add statistics
  dma/ioat: add support for vchan status function
  dma/ioat: add burst capacity function
  devbind: move ioat device IDs to dmadev category
  raw/ioat: deprecate ioat rawdev driver
