Merge tag 'dmaengine-5.4-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:
- Move Dmaengine DT bindings to YAML and convert Allwinner to schema.
- FSL dma device_synchronize implementation
- DW split acpi and of helpers and updates to driver and support for
Elkhart Lake
- Move filter fn as private for omap-dma and edma drivers and
improvements to these drivers
- Mark expected switch fall-through in couple of drivers
- Renames of shdma and nbpfaxi binding document
- Minor updates to bunch of drivers
