2017-03-28soc: qcom: smd: Remove standalone driverBjorn Andersson
Remove the standalone SMD implementation as we have transitioned the client drivers to use the RPMSG based one. Also remove all dependencies on QCOM_SMD from Kconfig files, in order to keep them selectable in the absence of the removed symbol.

2017-03-28soc: qcom: smd: Transition client drivers from smd to rpmsgBjorn Andersson
By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.

2017-02-23Merge tag 'rproc-v4.11' of git://github.com/andersson/remoteprocLinus Torvalds
Pull remoteproc updates from Bjorn Andersson: "This introduces support for booting the dedicated sensor core in the Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to utilize SMD subdevice helpers for properly handle shutdowns and restarts of the remoteproc, add virtio support to the ST remoteproc and refactor the Qualcomm Hexagon driver to handle variations between platforms. The support code for parsing, loading and authenticating Qualcomm firmware files (MDT) is refactored and move to drivers/soc/qcom, to allow for non-remoteproc drivers to utilize this. Finally it brings some cleanups to the remoteproc core" * tag 'rproc-v4.11' of git://github.com/andersson/remoteproc: (27 commits) remoteproc: qcom: mdt_loader: Use signed type for offset remoteproc: st: add virtio communication support remoteproc: st: correct probe error management remoteproc: Modify the function names remoteproc: Reduce asynchronous request_firmware to auto-boot only remoteproc: Drop qcom_scm_pas_supported() from adsp_probe() MAINTAINERS: Add missing rpmsg include path remoteproc: qcom: Use common SMD edge handler remoteproc: qcom: wcnss: Make SMD handling common remoteproc: Move qcom_mdt_loader into drivers/soc/qcom remoteproc: qcom: mdt_loader: Refactor MDT loader remoteproc: qcom: mdt_loader: Don't overwrite firmware object remoteproc: qcom: Extract non-mdt related helper remoteproc: qcom: q6v5: Decouple driver from MDT loader remoteproc: qcom: q6v5: Remove mss supply from 8916 remoteproc: qcom: fix initializers for qcom_mss_reg_res array remoteproc: Drop firmware_loading_complete remoteproc: Add RPROC_DELETED state remoteproc: Move rproc_delete_debug_dir() to rproc_del() remoteproc: qcom: Add SLPI rproc support to load and boot slpi proc. ...

2016-08-23soc: qcom: smd: Represent smd edges as devicesBjorn Andersson
By representing each edge as its own device the channels are no longer tied to being parented by the same smd device and as such an edge can live as children of e.g. remoteproc instances. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
2016-08-23soc: qcom: smd: Simplify multi channel handlingBjorn Andersson
Multi-channel clients split between several drivers need a way to close individual channels, as these drivers might be removed individually. With this in place the responsibility of closing additionally opened channels to the client as well only concerning smd about the primary channel. With this approach we will only trigger removal of SMD devices based on the state of the primary channel, however we get in sync with how rpmsg works.

2016-06-24soc: qcom: wcnss_ctrl: Make wcnss_ctrl parent the other componentsBjorn Andersson
We need the signal from wcnss_ctrl indicating that the firmware is up and running before we can communicate with the other components of the chip. So make these other components children of the wcnss_ctrl device, so they can be probed in order. The process seems to take between 1/2-5 seconds, so this is done in a worker, instead of holding up the probe.

2015-10-14soc: qcom: Make qcom_smem_get() return a pointerStephen Boyd
Passing a void ** almost always requires a cast at the call site. Instead of littering the code with casts every time this function is called, have qcom_smem_get() return a void pointer to the location of the smem item. This frees the caller from having to cast the pointer.
