media: vimc: Add vimc-streamer for stream control

2019-02-07T17:23:09Z

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: fill in correct driver name in querycap

2019-01-21T17:45:01Z

The driver name as returned in v4l2_capabilities must be vimc, not vimc_capture. Fix this. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vimc: add test_pattern and h/vflip controls to the sensor

2017-12-08T15:44:55Z

Add support for the test_pattern control and the h/vflip controls. This makes it possible to switch to more interesting test patterns and to test control handling in v4l-subdevs. There are more tpg-related controls that can be added, but this is a good start.

[media] vimc: Subdevices as modules

2017-06-23T12:12:07Z

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.
