2016-09-08rpmsg: Allow callback to return errorsBjorn Andersson
Some rpmsg backends support holding on to and redelivering messages upon failed handling of them, so provide a way for the callback to report and error and allow the backends to handle this. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-09-08rpmsg: Clean up rpmsg device vs channel namingBjorn Andersson
The rpmsg device representing struct is called rpmsg_channel and the variable name used throughout is rpdev, with the communication happening on endpoints it's clearer to just call this a "device" in a public API. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-09-08rpmsg: rpmsg_send() operations takes rpmsg_endpointBjorn Andersson
The rpmsg_send() operations has been taking a rpmsg_device, but this forces users of secondary rpmsg_endpoints to use the rpmsg_sendto() interface - by extracting source and destination from the given data structures. If we instead pass the rpmsg_endpoint to these functions a service can use rpmsg_sendto() to respond to messages, even on secondary endpoints. In addition this would allow us to support operations on multiple channels in future backends that does not support off-channel operations. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-08-12samples/rpmsg: add support for multiple instancesAnna, Suman
The current rpmsg_client_sample is a very simple example and is not designed to handle multiple instances. Add support for multiple instances, so that the same number of pings are sent to each instance. The instances can be on one or multiple remote processors.

Existing drivers and examples are updated to use the module_rpmsg_driver helper macro. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-05-06rpmsg: drop owner assignment from rpmsg_driversAndrew F. Davis
An rpmsg_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2013-01-03misc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the last of the __dev* markings from the kernel from a variety of different, tiny, places. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-02-08samples/rpmsg: add an rpmsg driver sampleOhad Ben-Cohen
Add an rpmsg driver sample, which demonstrates how to communicate with an AMP-configured remote processor over the rpmsg bus. Note how once probed, the driver can immediately start sending messages using the rpmsg_send() API, without having to worry about creating endpoints or allocating rpmsg addresses: all that work is done by the rpmsg bus, and the required information is already embedded in the rpmsg channel that the driver is probed with. In this sample, the driver simply sends a "Hello World!" message to the remote processor repeatedly. Designed with Brian Swetland <swetland@google.com>.
