media: vimc: Remove unused but set variables

media: vimc: Add vimc-streamer for stream control

2019-03-23T13:35:30+00:00

commit adc589d2a20808fb99d46a78175cd023f2040338 upstream. Add a linear pipeline logic for the stream control. It's created by walking backwards on the entity graph. When the stream starts it will simply loop through the pipeline calling the respective process_frame function of each entity.

media: vimc: constify video_subdev structures

2017-08-20T12:04:30+00:00

These structures are all only stored in fields of v4l2_subdev_ops structures, all of which are const, so these structures can be const as well. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vimc: set id_table for platform drivers

2017-07-17T14:26:56+00:00

The vimc platform drivers define a platform device ID table but these are not set to the .id_table field in the platform driver structure. So the platform device ID table is only used to fill the aliases in the module but are not used for matching (works because the platform subsystem fallbacks to the driver's name if no .id_table is set). But this also means that the platform device ID table isn't used if the driver is built-in, which leads to the following build warning: This causes the following build warnings when the driver is built-in: drivers/media/platform/vimc//vimc-capture.c:528:40: warning: ‘vimc_cap_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_cap_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-debayer.c:588:40: warning: ‘vimc_deb_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_deb_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-scaler.c:442:40: warning: ‘vimc_sca_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_sca_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-sensor.c:376:40: warning: ‘vimc_sen_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_sen_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ Reported-by: Mauro Carvalho Chehab Suggested-by: Sakari Ailus Signed-off-by: Javier Martinez Canillas Reviewed-by: Helen Koike Acked-by: Sakari Ailus

[media] vimc: Subdevices as modules

2017-06-23T12:12:07+00:00

Change the core structure for adding subdevices in the topology. Instead of calling the specific create function for each subdevice, inject a child platform_device with the driver's name. Each type of node in the topology (sensor, capture, debayer, scaler) will register a platform_driver with the corresponding name through the component subsystem. Implementing a new subdevice type doesn't require vimc-core to be altered. This facilitates future implementation of dynamic entities, where hotpluging an entity in the topology is just a matter of registering/unregistering a platform_device in the system. It also facilitates other implementations of different nodes without touching the core code and remove the need of a header file for each type of node.
