* remoteproc: rename subdev probe and remove functionsAlex Elder2018-06-261-8/+8
| | | | | | | | | Rename functions used when subdevices are started and stopped to reflect the new naming scheme. Tested-by: Fabien Dessenne <fabien.dessenne@st.com> Signed-off-by Alex Elder <elder@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
* remoteproc: Make client initialize ops in rproc_subdevBjorn Andersson2018-06-261-8/+10
| | | | | | | | | | | | | In preparation of adding the additional prepare and unprepare operations make the client responsible for filling out the function pointers of the rproc_subdev. This makes the arguments to rproc_add_subdev() more manageable, in particular when some of the functions are left out.

* remoteproc: fix null pointer dereference on glink only platformsSibi Sankar2018-04-051-0/+6
| | | | | | | | | Currently calling list_del on smd subdev remove path results in null pointer dereference on glink only platforms. Fix this by adding safety checks in glink/smd subdev remove paths.

* remoteproc: Pass type of shutdown to subdev removeBjorn Andersson2018-02-121-3/+3
| | | | | | | | | | remoteproc instances can be stopped either by invoking shutdown or by an attempt to recover from a crash. For some subdev types it's expected to clean up gracefully during a shutdown, but are unable to do so during a crash - so pass this information to the subdev remove functions.

| | | | | | | | | | | | | | | | | | As the core now deals with the lack of a resource table, remove the dangling custom dummy implementations of find_rsc_table from drivers.

|/ | | | | | | | | | | | This adds the remoteproc part of subsystem restart, which is responsible for emitting notifications to other processors in the system about a dying remoteproc instance. These notifications are propagated to the various communication systems in the various remote processors to shut down communication links that was left in a dangling state as the remoteproc was stopped (or crashed).
