[media] v4l2: use new flag to enable core priority handling

2011-03-22T19:38:16+00:00

Rather than guess which driver supports core priority handling, require drivers
that do to explicitly set the V4L2_FL_USE_FH_PRIO flag in video_device.

Updated the core prio handling accordingly and set the flag in the three
drivers that do.

[media] v4l: subdev: Generic ioctl support

2011-03-22T07:53:45+00:00

Instead of returning an error when receiving an ioctl call with an
unsupported command, forward the call to the subdev core::ioctl handler.

[media] v4l: Make v4l2_subdev inherit from media_entity

2011-03-22T07:53:20+00:00

V4L2 subdevices are media entities. As such they need to inherit from
(include) the media_entity structure.

When registering/unregistering the subdevice, the media entity is
automatically registered/unregistered. The entity is acquired on device
open and released on device close.

[media] v4l: Make video_device inherit from media_entity

[media] v4l: Add a media_device pointer to the v4l2_device structure

2011-03-22T07:53:18+00:00

The pointer will later be used to register/unregister media entities
when registering/unregistering a v4l2_subdev or a video_device.

With the introduction of media devices, device drivers need to store a
pointer to a driver-specific structure in the device's drvdata.
v4l2_device can't claim ownership of the drvdata anymore.

To maintain compatibility with drivers that rely on v4l2_device storing
a pointer to itself in the device's drvdata, v4l2_device_register() will
keep doing so if the drvdata is NULL.

[media] v4l: subdev: Events support

Provide v4l2_subdevs with v4l2_event support. Subdev drivers only need very
little to support events.
