Hi everybody,
Here's the sixth version of the V4L2 subdev userspace API patches. The patches
have been rebased on top of 2.6.37, and support for the control framework has
been integrated.

The two functions are mostly identical. They handle the copy_from_user

video_usercopy and video_ioctl2, and call that function from both.

Hi everybody,
Here is the eighth version of the media controller core and V4L2 patches.
Quick reminder for those who missed the previous version. let me quote the
documentation (Documentation/DocBook/v4l/media-controller.xml).
Discovering a [media] device internal topology, and configuring it
Due to the wide differences between drivers regarding power management
needs, the media controller does not implement power management.
However, the media_entity structure includes a use_count field that
media drivers can use to track the number of users of every entity for
power management needs.
Create the following ioctl and implement it at the media device level to
query device information.
- MEDIA_IOC_DEVICE_INFO: Query media device information
The ioctl and its data structure are defined in the new kernel header
linux/media.h available to userspace applications.
Signed-off-by:
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.

Signed-off-by: Laurent Pinchart
The v4l2_mbus_framefmt structure will be part of the public userspace
API and used (albeit indirectly) as an ioctl argument. As such, its size
must be fixed across userspace ABIs.
Replace the v4l2_field and v4l2_colorspace enums by __u32 fields and add
padding for future enhancements.
Hi everybody,
Here's the sixth version of the sub-device pad-level operations patches.
The patches are just rebased on top of 2.6.37 and some more padding has
