Merge tag 'dmaengine-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine updates from Vinod Koul:
"Core:
- Mark dma_request_slave_channel() deprecated in favour of
dma_request_chan()
- subsystem conversion for tasklet_setup() API
- subsystem removal of local dma_parms for arm drivers
Also updates to bunch of driver notably TI, DW and AXI-DMAC"
