Merge tag 'dmaengine-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine

Pull dmaengine updates from Vinod Koul:
 "A bunch of new support and few updates to drivers:

  New support:
   - DMA_MEMCPY_SG support is bought back as we have a user in Xilinx
     driver
   - Support for TI J721S2 SoC in k3-udma driver
   - Support for Ingenic MDMA and BDMA in the JZ4760
   - Support for Renesas r8a779f0 dmac

  Updates:
   - We are finally getting rid of slave_id, so this brings in the
     changes across tree for that
   - updates for idxd driver
   - at_xdmac driver cleanup"
