[media] V4L: add media bus configuration subdev operations

2011-07-27T20:56:08+00:00

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.

[media] v4l: Move the media/v4l2-mediabus.h header to include/linux

2011-03-22T07:53:21+00:00

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.

V4L/DVB: mediabus: fix ambiguous pixel code names

2010-08-02T19:43:36+00:00

Endianness notation is meaningless for 8 bit YUYV codes. Switch pixel code
names to explicitly state the order of colour components in the data
stream.

V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel and frame formats

2009-12-16T11:27:27+00:00

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.
