[PATCH v5 1/3] dmaengine: ptdma: Initial driver for the AMD PTDMA controller

2020-06-16 Thread Sanjay R Mehta
From: Sanjay R Mehta This driver add support for AMD PTDMA controller. This device 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
