[PATCH v4 0/4] remoteproc: Panic handling

[Bjorn Andersson]

Add support for invoking a panic handler in remoteproc drivers, to allow them
to invoke e.g. cache flushing on the remote processors in response to a kernel
panic - to aid in post mortem debugging of system issues.

Bjorn Andersson (4):
  remoteproc: Traverse rproc_list under RCU read lock
  remoteproc: Introduce "panic" callback in ops
  remoteproc: qcom: q6v5: Add common panic handler
  remoteproc: qcom: Introduce panic handler for PAS and ADSP
