Linus Torvalds 708283abf8 Merge tag 'dmaengine-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine updates from Vinod Koul:
 "New controller support and updates to drivers.

  New support:
   - Qualcomm SM6115 and QCM2290 dmaengine support
   - at_xdma support for microchip,sam9x7 controller

  Updates:
   - idxd updates for wq simplification and ats knob updates
   - fsl edma updates for v3 support
   - Xilinx AXI4-Stream control support
   - Yaml conversion for bcm dma binding"
