2021-08-29dmaengine: ptdma: Initial driver for the AMD PTDMASanjay R Mehta
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.
