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: Move qcom_mdt_loader into drivers/soc/qcomBjorn Andersson
With the remoteproc parts cleaned out of the MDT loader we can move it to drivers/soc/qcom. Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-02-06remoteproc: qcom: mdt_loader: Refactor MDT loaderBjorn Andersson
Pushing the SCM calls into the MDT loader reduces duplication in the callers and allows for non-remoteproc clients to use the helper for parsing and loading MDT files. Cc: Andy Gross <andy.gross@linaro.com> 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>
2016-11-14remoteproc: qcom_wcnss: Fix circular module dependencyBjorn Andersson
The tie between the main WCNSS driver and the IRIS driver causes a circular dependency between the two modules. Neither part makes sense to have on their own so lets merge them into one module. For the sake of picking up the clock and regulator resources described in the iris of_node we need an associated struct device. But, to keep the size of the patch down we continue to represent the IRIS part as its own platform_driver, within the same module, rather than setting up a dummy device.

2016-11-14remoteproc: wcnss: Bond SMD edge to remoteprocBjorn Andersson
Allow the wcnss smd edge to be described as a child of the wcnss remoteproc node and make the edge life cycle follow the running state of the remoteproc. This bond is necessary to clean up the smd state when the remote processor is suddenly removed, and in some cases even when it shut down in a controlled fasion.

2016-10-18remoteproc: qcom: wcnss: Fix module autoloadJavier Martinez Canillas
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/remoteproc/qcom_wcnss.ko | grep alias $ After this patch: $ modinfo drivers/remoteproc/qcom_wcnss.ko | grep alias alias: of:N*T*Cqcom,pronto-v2-pilC* alias: of:N*T*Cqcom,pronto-v2-pil alias: of:N*T*Cqcom,pronto-v1-pilC* alias: of:N*T*Cqcom,pronto-v1-pil alias: of:N*T*Cqcom,riva-pilC* alias: of:N*T*Cqcom,riva-pil Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-10-02remoteproc: Split driver and consumer dereferencingBjorn Andersson
In order to be able to lock a rproc driver implementations only when used by a client, we must differ between the dereference operation of a client and the implementation itself. This patch brings no functional change. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-08-22remoteproc: qcom: wcnss: Fix return value check in wcnss_probe()Wei Yongjun
In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-08-18remoteproc: qcom: Introduce WCNSS peripheral image loaderBjorn Andersson
This introduces the peripheral image loader, for loading WCNSS firmware and boot the core on e.g. MSM8974. The firmware is verified and booted with the help of the Peripheral Authentication System (PAS) in TrustZone.
