#     Merge tag 'dmaengine-5.6-rc1' of git://git.infradead.org/users/vkoul/slave-dma
#     
#     Pull dmaengine updates from Vinod Koul:
#      "This time we have a bunch of core changes to support dynamic channels,
#       hotplug of controllers, new apis for metadata ops etc along with new
#       drivers for Intel data accelerators, TI K3 UDMA, PLX DMA engine and
#       hisilicon Kunpeng DMA engine. Also usual assorted updates to drivers.
#     
#       Core:
#        - Support for dynamic channels
#        - Removal of various slave wrappers
#        - Make few slave request APIs as private to dmaengine
#        - Symlinks between channels and slaves
#        - Support for hotplug of controllers
#        - Support for metadata_ops for dma_async_tx_descriptor
#        - Reporting DMA cached data amount
#        - Virtual dma channel locking updates
#     
#       New drivers/device/feature support support:
#        - Driver for Intel data accelerators
#        - Driver for TI K3 UDMA
#        - Driver for PLX DMA engine
#        - Driver for hisilicon Kunpeng DMA engine
#        - Support for eDMA support for QorIQ LS1028A in fsl edma driver
#        - Support for cyclic dma in sun4i driver
#        - Support for X1830 in JZ4780 driver"
