2017-12-18media: v4l2-dev: convert VFL_TYPE_* into an enumMauro Carvalho Chehab
Using enums makes easier to document, as it can use kernel-doc markups. It also allows cross-referencing, with increases the kAPI readability. Please notice that now cx88_querycap() has to have a default for the VFL type, as there are more types than supported by the driver.

2017-12-18media: v4l2-mediabus: use BIT() macro for flagsMauro Carvalho Chehab
Instead of using (1 << n) for bits, use the BIT() macro, as it makes a difference from documentation point of view. Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2015-06-05[media] videodev2.h: add support for transfer functionsHans Verkuil
In the past the transfer function was implied by the colorspace. However, it is an independent entity in its own right. Add support for explicitly choosing the transfer function. This change will allow us to represent linear RGB (as is used by openGL), and it will make it easier to work with decoded video material since most codecs store the transfer function as a separate property as well.

2011-09-24[media] v4l2: Add polarity flag definitions for the parallel bus FIELD signalSylwester Nawrocki
FIELD signal is used for indicating frame field type to the frame grabber in interlaced scan mode, as specified in ITU-R BT.601 standard. In normal operation mode FIELD = 0 selects Field1 (odd) and FIELD = 1 selects Field2 (even). When the FIELD signal is inverted it's the other way around. Add corresponding flags for configuring the FIELD signal polarity, V4L2_MBUS_FIELD_EVEN_HIGH for the standard (non-inverted) case and V4L2_MBUS_FIELD_EVEN_LOW for inverted case. Also add a comment about usage of V4L2_MBUS_[HV]SYNC* flags for the hardware that uses [HV]REF signals.

2011-07-27[media] V4L: add media bus configuration subdev operationsGuennadi Liakhovetski
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.

2011-03-22[media] v4l: Move the media/v4l2-mediabus.h header to include/linuxLaurent Pinchart
The header defines the v4l2_mbus_framefmt structure which will be used by the V4L2 subdevs userspace API. Change the type of the v4l2_mbus_framefmt::code field to __u32, as enum sizes can differ between different ABIs on the same architectures.

2009-12-16V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel ↵Guennadi Liakhovetski
and frame formats Video subdevices, like cameras, decoders, connect to video bridges over specialised busses. Data is being transferred over these busses in various formats, which only loosely correspond to fourcc codes, describing how video data is stored in RAM. This is not a one-to-one correspondence, therefore we cannot use fourcc codes to configure subdevice output data formats. This patch adds codes for several such on-the-bus formats and an API, similar to the familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those codes. After all users of the old API in struct v4l2_subdev_video_ops are converted, it will be removed. Also add helper routines to support generic pass-through mode for the soc-camera framework. create mode 100644 drivers/media/video/soc_mediabus.c create mode 100644 include/media/soc_mediabus.h create mode 100644 include/media/v4l2-mediabus.h Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
