Merge tag 'dmaengine-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine updates from Vinod Koul:
"This time around we have a smaller pull request than usual and this
includes code removal, so should be good!
New drivers/devices
- Support for QCOM SM8250 GPI DMA
- removal of shdma-of driver and binding
Updates:
- arm-pl08x yaml binding move
- altera-msgdma gained DT support
- removal of imx-sdma platform data support
- idxd and xilinx driver updates"
