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.
Changes in v2:
- Changed all variants of "mb" to "dma_mb.
- Changed cancel_delayed_work to cancel_delayed_work_sync.
- Removed 32bit dma_set_mask_and_coherent.
- Rearrange the order of the #include directives alphabetically.
