* remoteproc: Drop wait in __rproc_boot()Bjorn Andersson2016-12-091-19/+3
| | | | | | | | | | | | | | In the event that rproc_boot() is called before the firmware loaded completion has been flagged it will wait with the mutex held, obstructing the request_firmware_nowait() callback from completing the wait. As rproc_fw_config_virtio() has been reduced to only triggering auto-boot there is no longer a reason for waiting in rproc_boot(), so drop this.

* remoteproc/ste: Delete unused driverJean Delvare2016-12-093-353/+0
| | | | | | | | | | | | | | | | | | | | Back in July 2014 I asked around what was the intended target platform for the STE Modem remoteproc driver, so that I could add the proper hardware dependency to its config option. The answer I got was that there was no known publicly available hardware needing it and it was unlikely that there ever would. So I think it's time to delete this driver to lower the maintenance burden.

* remoteproc: Remove "experimental" warningBjorn Andersson2016-12-091-3/+0
| | | | | | | | | | | Warning users that remoteproc and it's binary format are under development doesn't serve much of a purpose. Different drivers support different image formats and the resource table has a version field that would need to be bumped when incompatible changes are introduced. So lets drop this warning to clean up the kernel log. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This avoids some nasty Kconfig recursive dependency issues. Also when using menuconfig client drivers will be hidden until the core has been enabled. Documentation/kbuild/kconfig-language.txt: Note: select should be used with care. select will force a symbol to a value without visiting the dependencies. By abusing select you are able to select a symbol FOO even if FOO depends on BAR that is not set. In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies. That will limit the usefulness but on the other hand avoid the illegal configurations all over.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | slim core is used as a basis for many IPs in the STi chipsets such as fdma and demux. To avoid duplicating the elf loading code in each device driver a slim rproc driver has been created. This driver is designed to be used by other device drivers such as fdma, or demux whose IP is based around a slim core. The device driver can call slim_rproc_alloc() to allocate a slim rproc and slim_rproc_put() when finished. This driver takes care of ioremapping the slim registers (dmem, imem, slimcore, peripherals), whose offsets and sizes can change between IP's. It also obtains and enables any clocks used by the device. This approach avoids having a double mapping of the registers as slim_rproc does not register its own platform device. It also maps well to device tree abstraction as it allows us to have one dt node for the whole device. All of the generic rproc elf loading code can be reused, and we provide start() stop() hooks to start and stop the slim core once the firmware has been loaded. This has been tested successfully with fdma driver. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

* | remoteproc: qcom: wcnss: Fix module autoloadJavier Martinez Canillas2016-10-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | remoteproc: Keep local copy of firmware nameMatt Redfearn2016-10-182-16/+17
|/ | | | | | | | | | | | | 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.
