When qcom_smd is a loadable module and wcnss-pil is built-in, we get a link error: drivers/remoteproc/qcom_wcnss_pil.o: In function `wcnss_smd_remove': qcom_wcnss_iris.c:(.text.wcnss_smd_remove+0x10): undefined reference to `qcom_smd_unregister_edge' drivers/remoteproc/qcom_wcnss_pil.o: In function `wcnss_smd_probe': qcom_wcnss_iris.c:(.text.wcnss_smd_probe+0x12): undefined reference to `qcom_smd_register_edge' This adds a Kconfig dependency to avoid this. We can still allow build-testing with SMD disabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

The newly added driver tries to 'select' a symbol that it has an implicit dependency on, which confuses Kconfig: subsection "Kconfig recursive dependency limitations" drivers/remoteproc/Kconfig:3: symbol REMOTEPROC is selected by QCOM_ADSP_PIL As REMOTEPROC is itself user-visible, we clearly should not select it from a driver, removing the line fixes the problem.

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.

As all vdev resources are allocated before we boot the remote processor we no longer need to support modifying the resource table while the remote is running. This saves us from the table_ptr dance, but more importantly allow the remote processor to enable security lock down of the loaded table memory region.

Instead of having the vrings being allocated and freed as they are requested by the virtio device tie their life cycle to the vdev resource. This allows us to decouple the vdev resource management from the virtio device management. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

Allow the associated smd edge to be described within the wcnss remoteproc node.

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.

This patch adds a sysfs interface to rproc allowing the firmware name and processor state to be changed dynamically. State was previously available in debugfs, and is replicated here. The firmware file allows retrieval of the running firmware name, and a new one to be specified at run time, so long as the remote processor has been stopped.

The newly added st_fdma driver introduces a build warning for allmodconfig when we add '-Wmaybe-uninitialized': drivers/dma/st_fdma.c: In function 'st_fdma_probe': drivers/dma/st_fdma.c:777:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized] The warning is correct, though this can't happen in practice as the check is redundant (we don't get to this function if the pointer is NULL). Even if the function were called with a NULL of_node, the check is not needed because of_property_read_u32 can deal with a NULL argument by returning an error. Removing the unnecessary code simplifies the function and avoids the condition that we get the warning for.

Storage of the firmware name was inconsistent, either storing a pointer to a name stored with unknown ownership, or a variable length tacked onto the end of the struct proc allocated in rproc_alloc. In preparation for allowing the firmware of an already allocated struct rproc to be changed, instead always keep a locally maintained copy of the firmware name.
