2017-06-06[media] v4l: flash led class: Use fwnode_handle instead of device_node in initSakari Ailus

2017-06-06[media] v4l: fwnode: Support generic fwnode for parsing standardised propertiesSakari Ailus
The fwnode_handle is a more generic way than OF device_node to describe firmware nodes. Instead of the OF API, use more generic fwnode API to obtain the same information. As the V4L2 fwnode support will be required by a small minority of e.g. ACPI based systems (the same might actually go for OF), make this a module instead of embedding it in the videodev module. The origins of the V4L2 fwnode framework is in the V4L2 OF framework.

2017-04-19[media] cec: Kconfig cleanupHans Verkuil
The Kconfig options for the CEC subsystem were a bit messy. In addition there were two cec sources (cec-edid.c and cec-notifier.c) that were outside of the media/cec directory, which was weird. Move those sources to media/cec as well. The cec-edid and cec-notifier functionality is now part of the cec module and these are no longer separate modules. Also remove the MEDIA_CEC_EDID config option and include it with the main CEC config option (which defined CEC_EDID anyway). Added static inlines to cec-edid.h for dummy functions when CEC_CORE isn't defined. CEC drivers should now depend on CEC_CORE. CEC drivers that need the cec-notifier functionality must explicitly select CEC_NOTIFIER. The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of CEC_CORE, fix that as well.

Drivers might try to access and run enable_source and disable_source handlers when the driver that implements these handlers is clearing the handlers during its unregister. Fix the following race condition: process 1 process 2 request video streaming unbind au0828 v4l2 checks if tuner is free ... ... au0828_unregister_media_device() ... ... (doesn't hold graph_mutex) mdev->enable_source = NULL; if (mdev && mdev->enable_source) mdev->disable_source = NULL; mdev->enable_source() (enable_source holds graph_mutex) As shown above enable_source check is done without holding the graph_mutex. If unbind happens to be in progress, au0828 could clear enable_source and disable_source handlers leading to null pointer de-reference. Fix it by protecting enable_source and disable_source set and clear and protecting enable_source and disable_source handler access and the call itself. process 1 process 2 request video streaming unbind au0828 v4l2 checks if tuner is free ... ... au0828_unregister_media_device() ... ... (hold graph_mutex while clearing) mdev->enable_source = NULL; if (mdev) mdev->disable_source = NULL; (hold graph_mutex to check and call enable_source) if (mdev->enable_source) mdev->enable_source() If graph_mutex is held to just heck for handler being null and needs to be released before calling the handler, there will be another window for the handlers to be cleared. Hence, enable_source and disable_source handlers no longer hold the graph_mutex and expect callers to hold it to avoid forcing them release the graph_mutex before calling the handlers.

2017-01-30[media] rc: change wakeup_protocols to list all protocol variantsSean Young
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

2017-01-27[media] media: Rename graph and pipeline structs and functionsSakari Ailus
The media_entity_pipeline_start() and media_entity_pipeline_stop() functions are renamed as media_pipeline_start() and media_pipeline_stop(), respectively. The reason is two-fold: the pipeline struct is, rightly, already called media_pipeline (rather than media_entity_pipeline) and what this really is about is a pipeline. A pipeline consists of entities --- and, well, other objects embedded in these entities. As the pipeline object will be in the future moved from entities to pads in order to support multiple pipelines through a single entity, do the renaming now. Similarly, functions operating on struct media_entity_graph as well as the struct itself are renamed by dropping the "entity_" part from the prefix of the function family and the data structure. The graph traversal which is what the functions are about is not specifically about entities only and will operate on pads for the same reason as the media pipeline. The patch has been generated using the following command: git grep -l media_entity |xargs perl -i -pe ' s/media_entity_pipeline/media_pipeline/g; s/media_entity_graph/media_graph/g' And a few manual edits related to line start alignment and line wrapping.

Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", <F>); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>
2016-11-29[media] cec: pass parent device in register(), not allocate()Hans Verkuil
The cec_allocate_adapter function doesn't need the parent device, only the cec_register_adapter function needs it. Drop the cec_devnode parent field, since devnode.dev.parent can be used instead. This change makes the framework consistent with other frameworks where the parent device is not used until the device is registered.

2016-11-18[media] v4l2-common: add a debug macro to be used with dev_foo()Mauro Carvalho Chehab
Currently, there's a mess at the V4L2 printk macros: some drivers use their own macros, others use pr_foo() or v4l_foo() macros, while more modern drivers use dev_foo() macros. The best is to get rid of v4l_foo() macros, as they can be replaced by either dev_foo() or pr_foo(). Yet, such change can be disruptive, as dev_foo() cannot use KERN_CONT. So, the best is to do such change driver by driver. There are replacements for most v4l_foo() macros, but it lacks a way to enable debug messages per level. So, add such macro, in order to make the conversion easier. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
