Subject: [PATCH 0/3] Add support for AMD AE4DMA controller driver

From: Sanjay R Mehta <sanju.mehta@....com>

This patch series add support for AMD AE4DMA controller which
performs high bandwidth memory-to-memory and IO copy operation,
performs DMA transfer through queue based descriptor management.

The AE4DMA controller allows for configuration of the number of
queues per controller, with a range from 1 to 16. This configuration
can be conveniently adjusted using the driver's "max_hw_q" parameter.

The AMD Processor features multiple ae4dma device instances,
with each controller supporting a maximum of 16 DMA queues.

Sanjay R Mehta (3):
  dmaengine: ae4dma: Initial ae4dma controller driver with multi channel
  dmaengine: ae4dma: register AE4DMA controller as a DMA resource
  dmaengine: ae4dma: Add debugfs entries for AE4DMA
