2014-07-17[media] v4l: vsp1: Setup control handler automatically at stream on timeLaurent Pinchart1-0/+39
When setting a control directly on a subdev node the VSP1 driver doesn't guarantee that the device is powered on. This leads to crashes when the control handlers writes to hardware registers. One easy way to fix this is to ensure that the device gets powered on when a subdev node is opened. However, this consumes power unnecessarily, as there's no need to power the device on when setting formats on the pipeline. Furthermore, control handler setup at entity init time suffers from the same problem as the device isn't powered on easier. Fix this by extend the entity base object to setup the control handler automatically when starting the stream. Entities must then skip writing to registers in the set control handler when not streaming, which can be tested with the new vsp1_entity_is_streaming() helper function.

2014-07-17[media] v4l: vsp1: Cleanup video nodes at removal timeLaurent Pinchart1-0/+3
Video nodes created and initialized in the RPF and WPF init code paths are never unregistered, and the related resources (videobuf alloc context and media entity) never released. Fix this by storing a pointer to the vsp1_video object in vsp1_entity and calling vsp1_video_cleanup() from vsp1_entity_destroy(). This also allows simplifying the init error code paths.

2013-08-18[media] v4l: Renesas R-Car VSP1 driverLaurent Pinchart1-0/+181
The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.
