Merge tag 'rproc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This adds support for controlling the PRU and R5F clusters on the TI
  AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP
  and the audio, compute and modem remoteprocs in the Qualcomm SC8180x
  platform.

  It fixes improper ordering of cdev and device creation of the
  remoteproc control interface and it fixes resource leaks in the error
  handling path of rproc_add() and the Qualcomm modem and wifi
  remoteproc drivers.

  Lastly it fixes a few build warnings and replace the dummy parameter
  passed in the mailbox api of the stm32 driver to something not living
  on the stack"
