Merge tag 'dmaengine-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine

Pull dmaengine updates from Vinod Koul:
 "We have couple of drivers removed a new driver and bunch of new device
  support and few updates to drivers for this round.

  New drivers/devices:
   - Intel LGM SoC DMA driver
   - Actions Semi S500 DMA controller
   - Renesas r8a779a0 dma controller
   - Ingenic JZ4760(B) dma controller
   - Intel KeemBay AxiDMA controller

  Removed:
   - Coh901318 dma driver
   - Zte zx dma driver
   - Sirfsoc dma driver

  Updates:
   - mmp_pdma, mmp_tdma gained module support
   - imx-sdma become modern and dropped platform data support
   - dw-axi driver gained slave and cyclic dma support"
