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.
NOTE: This patchset has several dependencies:
- v26 of the dmadev set [1]
- v7 of the dmadev test suite [2]
- v7 of the IDXD driver [3]
