[media] videodev2.h: fix incorrect V4L2_DV_FL_HALF_LINE bitmask

2013-04-14T22:56:07+00:00

This was set to 1 << 0 which is the same as V4L2_DV_FL_REDUCED_BLANKING.
It should be 1 << 3 instead. Luckily interlaced formats are rarely used,
which is why this bug wasn't seen until now.

[media] v4l2: drop V4L2_CHIP_MATCH_SUBDEV_NAME

2013-04-14T22:46:02+00:00

After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.

[media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl

2013-03-25T12:31:05+00:00

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.

Define video buffer flag for the COPY timestamp. In this case the timestamp
value is copied from the OUTPUT to the corresponding CAPTURE buffer.

[media] Move DV-class control IDs from videodev2.h to v4l2-controls.h

2013-02-05T20:00:00+00:00

When the control IDs were split off from videodev2.h to v4l2-controls.h
these new Digital Video controls were forgotten (the two patches may
have crossed one another).
Move these controls to their proper place in v4l2-controls.h.

[media] v4l2-ctrl: Add helper function for the controls range update

2013-02-05T17:04:06+00:00

This patch adds a helper function that allows to modify range,
i.e. minimum, maximum, step and default value of a v4l2 control,
after the control has been created and initialized. This is helpful
in situations when range of a control depends on user configurable
parameters, e.g. camera sensor absolute exposure time depending on
an output image resolution and frame rate.
v4l2_ctrl_modify_range() function allows to modify range of an
INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.
Based on a patch from Hans Verkuil http://patchwork.linuxtv.org/patch/8654.
