Subject: [PATCH v3 0/4] remoteproc: Improvement for the Qualcomm sysmon

The core part of this series is the update to the sysmon driver to ensure that
notifications sent to the remote processor are consistent and always present
valid state transitions.

In testing this I finally took the time to fix up the issue of the SMP2P based
graceful shutdown in the remoteproc drivers always timing out if sysmon has
already successfully shut down the remote processor.

Bjorn Andersson (4):
  remoteproc: sysmon: Ensure remote notification ordering
  remoteproc: sysmon: Expose the shutdown result
  remoteproc: qcom: q6v5: Query sysmon before graceful shutdown
  remoteproc: sysmon: Improve error messages
