dmaengine: ptdma: Utilize the AE4DMA engine's multi-queue functionality (2025-03-11 02:33:27 +0530)
----------------------------------------------------------------
dmaengine updates for v6.15
New support:
- Microchip sama7d65 dma controller
- Yaml conversion of atmel dma binding and Freescale Elo DMA Controller
binding
Core:
- Remove device_prep_dma_imm_data() API as users are removed
- Reduce scope of some less frequently used DMA request channel APIs with
aim to cleanup these in future
