Merge tag 'dmaengine-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine

Pull dmaengine updates from Vinod Koul:
 "Core:

   - New API to combine configuration and preparation and users

  New hardware support:

   - Mediatek MT8189 SoC uart dma support

  Updates:

   - Designware dma driver flatten desc structures and simplify code,
     interrupt-path groundwork changes, first part of PCI EP DMA support

   - Updates to zynqmp_dma with runtime PM and device removal
     improvments

   - Xilinx dma optimizations for AXIDMA and MCDMA channel management"
