Merge tag 'dmaengine-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine updates from Vinod Koul:
"A bunch of driver updates, no new driver or controller support this
time though:
- Another pile of idxd updates
- pm routines cleanup for at_xdmac driver
- Correct handling of callback_result for few drivers
- zynqmp_dma driver updates and descriptor management refinement
- Hardware handshaking support for dw-axi-dmac
- Support for remotely powered controllers in Qcom bam dma
- tegra driver updates"
