dmaengine: ptdma: Initial driver for the AMD PTDMA2021-08-29T13:44:20ZSanjay R Mehtasanju.mehta@amd.com2021-08-17T13:55:57Zurn:sha1:fa5d823b16a9442d609617abeec31da8b6afa224
Add support for AMD PTDMA controller. It performs high-bandwidth
memory to memory and IO copy operation. Device commands are managed
via a circular queue of 'descriptors', each of which specifies source
and destination addresses for copying a single buffer of data.
