* [media] videodev2: Set vb2_rect's width and height as unsignedRicardo Ribalda2014-01-071-2/+2
| | | | | | | | | | | | | | As discussed on the media summit 2013, there is no reason for the width and height to be signed. Therefore this patch is an attempt to convert those fields from __s32 to __u32.

* [media] videodev2.h: defines to calculate blanking and frame sizesHans Verkuil2013-08-181-0/+10
| | | | | | | | | It is very common to have to calculate the total width and height of the blanking and the full frame, so add a few defines that deal with that.

* [media] v4l: Add V4L2_PIX_FMT_NV16M and V4L2_PIX_FMT_NV61M formatsLaurent Pinchart2013-08-181-0/+2
| | | | | | | | | | | | | NV16M and NV61M are planar YCbCr 4:2:2 and YCrCb 4:2:2 formats with a luma plane followed by an interleaved chroma plane. The planes are not required to be contiguous in memory, and the formats can only be used with the multi-planar formats API.

* [media] v4l2: drop V4L2_CHIP_MATCH_SUBDEV_NAMEHans Verkuil2013-04-141-2/+1
| | | | | | | | | | | 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 ioctlHans Verkuil2013-03-251-9/+25
| | | | | | | | | | | | | 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.

* [media] v4l2-ctrl: Add helper function for the controls range updateSylwester Nawrocki2013-02-051-0/+1
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | Define video buffer flags for different timestamp types. Everything up to now have used either realtime clock or monotonic clock, without a way to tell which clock the timestamp was taken from. Also document that the clock source of the timestamp in the timestamp field depends on buffer flags.
