Merge tag 'rproc-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
 "This fixes a race condition in the user space interface for starting
  and stopping remote processors, it makes the ELF loader properly skip
  zero memsz segments and it cleans up the debugfs tracefile code a bit
  by not checking for errors.

  It introduces support for controlling the audio DSP on Qualcomm
  MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP.

  It makes it possible to specify the firmware path for Mediatek's
  remote processors, fixes a double free in the SCP driver and addresses
  an issue with the SRAM initialization on MT8195.

  Lastly it deprecates the custom ELF loader in the iMX remoteproc
  driver, in favor of using the shared one"
