Merge tag 'rproc-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:

- Make the Xilinx remoteproc driver support running on only a single
core, disable still unsupported remoteproc features, and stop the
remoteproc on shutdown to facilitate kexec.

- Conclude the renaming of the Qualcomm ADSP driver to "PAS" that was
started many years ago.
