Merge tag 'rproc-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "Qualcomm SM8650 audio, compute and modem remoteproc are added.
  Qualcomm X1 Elite audio and compute remoteprocs are added, after
  support for shutting down the bootloader-loaded firmware loaded into
  the audio DSP..

  A dozen drivers in the subsystem are transitioned to use devres
  helpers for remoteproc and memory allocations - this makes it possible
  to acquire in-kernel handle to individual remoteproc instances in a
  cluster.

  The release of DMA memory for remoteproc virtio is corrected to ensure
  that restarting due to a watchdog bite doesn't attempt to allocate the
  memory again without first freeing it.

  Last, but not least, a couple of DeviceTree binding cleanups"
