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")
