f9b0366f5e dmaengine: ti: k3-udma: Use soc_device_match() for SoC dependent parameters 
Use separate data for SoC dependent parameters. These parameters depends
on the DMA integration (either in HW or in SYSFW), the DMA controller
itself remains compatible with either the am654 or j721e variant.

j7200 have the same DMA as j721e with different number of channels, which
can be queried from HW, but SYSFW defines different rchan_oes_offset
number for j7200 (0x80) compared to j721e (0x400).

b7fccfee1b dmaengine: imx-sdma: Drop local dma_parms 
Since commit 9495b7e92f ("driver core: platform: Initialize dma_parms
for platform devices"), struct platform_device already provides a
dma_parms structure, so we can save allocating another one.

8f6b6d0606 dmaengine: sf-pdma: Fix an error that calls callback twice 
Because a callback is called twice when DMA transfer complete
the second callback may be possible to access a freed memory
if the first callback routines perform the dma_release_channel function.
So this patch serialized the callback functions

Pull more io_uring fixes from Jens Axboe:
 "Two followup fixes. One is fixing a regression from this merge window,
  the other is two commits fixing cancelation of deferred requests.

  Both have gone through full testing, and both spawned a few new
  regression test additions to liburing.

   - Don't play games with const, properly store the output iovec and
     assign it as needed.

   - Deferred request cancelation fix (Pavel)"

   when memory encryption is active and disallow using IOMMUv2
   functionality.  This makes the AMDGPU driver work when memory
   encryption is active.

 - two more fixes for AMD IOMMU to fix updating the Interrupt Remapping

b7ddce3cbf io_uring: fix cancel of deferred reqs with ->files 
While trying to cancel requests with ->files, it also should look for
requests in ->defer_list, otherwise it might end up hanging a thread.

Cancel all requests in ->defer_list up to the last request there with
matching ->files, that's needed to follow drain ordering semantics.
