AMD AE4DMA Controller is a multi-queue DMA controller. Its design differs
significantly from PTDMA controller, although some functionalities
overlap. All functionalities similar to PTDMA are extended and merged
within PTDMA code to support both PTDMA and AE4DMA for code reuse. A new
AE4DMA driver directory is created to house unique AE4DMA code, ensuring
efficient handling of AE4DMA functionalities.

Basavaraj Natikar (7):
  dmaengine: Move AMD DMA driver to separate directory
  dmaengine: ae4dma: Add AMD ae4dma controller driver
  dmaengine: ptdma: Move common functions to common code
  dmaengine: ptdma: Extend ptdma to support multi-channel and version
  dmaengine: ae4dma: Register AE4DMA using pt_dmaengine_register
  dmaengine: ptdma: Extend ptdma-debugfs to support multi-queue
  dmaengine: ae4dma: Register debugfs using ptdma_debugfs_setup
