Pull rpmsg updates from Bjorn Andersson: "This extends the Qualcomm GLINK implementation to support the additional features used for communicating with modem and DSP coprocessors in modern Qualcomm platforms. In addition to this there's support for placing virtio RPMSG buffers in non-System RAM" * tag 'rpmsg-v4.14' of git://github.com/andersson/remoteproc: (29 commits) rpmsg: glink: initialize ret to zero to ensure error status check is correct rpmsg: glink: fix null pointer dereference on a null intent dt-bindings: soc: qcom: Extend GLINK to cover SMEM remoteproc: qcom: adsp: Allow defining GLINK edge rpmsg: glink: Export symbols from common code rpmsg: glink: Release idr lock before returning on error rpmsg: glink: Handle remote rx done command rpmsg: glink: Request for intents when unavailable rpmsg: glink: Use the intents passed by remote rpmsg: glink: Receive and store the remote intent buffers rpmsg: glink: Add announce_create ops and preallocate intents rpmsg: glink: Add rx done command rpmsg: glink: Make RX FIFO peak accessor to take an offset rpmsg: glink: Use the local intents when receiving data rpmsg: glink: Add support for TX intents rpmsg: glink: Fix idr_lock from mutex to spinlock rpmsg: glink: Add support for transport version negotiation rpmsg: glink: Introduce glink smem based transport rpmsg: glink: Do a mbox_free_channel in remove rpmsg: glink: Return -EAGAIN when there is no FIFO space ...
2017-09-01remoteproc: qcom: Make ssr_notifiers localBjorn Andersson
The ssr_notifiers variable should be local, so add the missing static storage classifier. Fixes: 1e140df04965 ("remoteproc: qcom: Add support for SSR notifications") Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-09-01remoteproc: qcom: adsp: Allow defining GLINK edgeBjorn Andersson
Introduce the GLINK subdev, which allows the definition of a GLINK edge as child of a remoteproc. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-08-29remoteproc: qcom: Use PTR_ERR_OR_ZEROHimanshu Jha
Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR Signed-off-by: Himanshu Jha <himanshujha199640@gmail.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-08-02remoteproc: qcom: Add support for SSR notificationsBjorn Andersson
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).

2017-02-06remoteproc: qcom: wcnss: Make SMD handling commonBjorn Andersson
Move the SMD edge handling to the Qualcomm common file to make it reusable for other Qualcomm remoteproc drivers. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-02-06remoteproc: qcom: Extract non-mdt related helperBjorn Andersson
In preparation for moving the mdt loader out of remoteproc let's move the somewhat unrelated resource table dummy helper to a Qualcomm "common" file. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
