      V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel and frame formats · 9a74251d
      Guennadi Liakhovetski 提交于
      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.
