[media] v4l: Implement v4l2_subdev_link_validate()

2012-05-14T11:45:31+00:00

v4l2_subdev_link_validate() is the default op for validating a link. In V4L2
subdev context, it is used to call a pad op which performs the proper link
check without much extra work.

[media] v4l: vdev_to_v4l2_subdev() should have return type "struct v4l2_subdev *"

2012-04-10T18:01:02+00:00

vdev_to_v4l2_subdev() should return struct v4l2_subdev *, not void *. Fix
this.

[media] v4l: VIDIOC_SUBDEV_S_SELECTION and VIDIOC_SUBDEV_G_SELECTION IOCTLs

2012-04-10T18:00:41+00:00

Add support for VIDIOC_SUBDEV_S_SELECTION and VIDIOC_SUBDEV_G_SELECTION
IOCTLs. They replace functionality provided by VIDIOC_SUBDEV_S_CROP and
VIDIOC_SUBDEV_G_CROP IOCTLs and also add new functionality (composing).

VIDIOC_SUBDEV_G_CROP and VIDIOC_SUBDEV_S_CROP continue to be supported.

[media] V4L: add .g_std() core V4L2 subdevice operation

2011-11-03T20:29:02+00:00

VIDIOC_G_STD can return the current TV-norm to the user in one of two ways:
if an .vidioc_g_std() ioctl operation is provided by the driver, it is
called, otherwise the value ot the .current_norm field of struct
video_device is returned. Since subdevice drivers currently have no access
to struct video_device objects, the only way to provide this information to
the user is by implementing a .g_std() method.

[media] V4L: dynamically allocate video_device nodes in subdevices

2011-11-03T20:29:01+00:00

Currently only very few drivers actually use video_device nodes, embedded
in struct v4l2_subdev. Allocate these nodes dynamically for those drivers
to save memory for the rest.

[media] V4L: add media bus configuration subdev operations

2011-07-27T20:56:08+00:00

Add media bus configuration types and two subdev operations to get
supported mediabus configurations and to set a specific configuration.
Subdevs can support several configurations, e.g., they can send video data
on 1 or several lanes, can be configured to use a specific CSI-2 channel,
in such cases subdevice drivers return bitmasks with all respective bits
set. When a set-configuration operation is called, it has to specify a
non-ambiguous configuration.
