Subject: [RFC 0/2] Allow client to recover crashed processor

The following 2 patches propose some changes to allow user space
client to shutdown and restart a crashed co-processor.
This is required when auto recovery is disabled at framework level or
when auto recovery procedure failed.

Sent as RFC as may be part of Mathieu's proposal for early boot/late
attach support

Loic Pallardy (2):
  remoteproc: sysfs: authorize rproc shutdown when rproc is crashed
  remoteproc: core: keep rproc in crash state in case of recovery
    failure
