Merge tag 'dmaengine-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine

Pull dmaengine updates from Vinod Koul:
 "The dmaengine subsystem updates for this cycle consist of a new driver
  (Microchip) along with couple of yaml binding conversions, core api
  updates and bunch of driver updates etc.

  New HW 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

  Updates:

   - Drop Fenghua Yu from idxd maintainers, as he changed jobs

   - AMD ptdma support for multiqueue and ae4dma deprecated PCI IDs
     removal"

+
+description:
+  The Atmel Direct Memory Access Controller (DMAC) transfers data from a source
+  peripheral to a destination peripheral over one or more AMBA buses. One channel
+  is required for each source/destination pair. In the most basic configuration,
+  the DMAC has one master interface and one channel. The master interface reads
+  the data from a source and writes it to a destination. Two AMBA transfers are
+  required for each DMAC data transfer. This is also known as a dual-access transfer.
+  The DMAC is programmed via the APB interface.
