2013-04-15[media] v4l2: drop V4L2_CHIP_MATCH_SUBDEV_NAMEHans Verkuil3-37/+5
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.

2013-04-15[media] v4l2: put VIDIOC_DBG_G_CHIP_NAME under ADV_DEBUGHans Verkuil1-0/+3
Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This prevents abuse from both userspace and kernelspace (some bridge drivers abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this ioctl).

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.

2013-01-24[media] dvb: Add DVBv5 statistics propertiesMauro Carvalho Chehab3-3/+181
The DVBv3 statistics parameters are limited on several ways: - It doesn't provide any way to indicate the used measure, so userspace need to guess how to calculate/use it; - Only a limited set of stats are supported; - Can't be called in a way to require them to be filled all at once (atomic reads from the hardware), with may cause troubles on interpreting them on userspace; - On some OFDM delivery systems, the carriers can be independently modulated, having different properties. Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places.
