remoteproc: Make client initialize ops in rproc_subdev

2018-06-26T20:53:07+00:00

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 platforms

2018-04-06T05:53:16+00:00

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 remove

2018-02-13T00:57:22+00:00

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.

remoteproc: Drop dangling find_rsc_table dummies

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

remoteproc: qcom: Make ssr_notifiers local

2017-09-01T22:42:29+00:00

The ssr_notifiers variable should be local, so add the missing static
storage classifier.
