V4L2 buffers use struct timeval with µs precision. Generally speaking, if us
precision is preferred elsewhere, the non-V4l2 specific portion could use
that. The conversion could be done in the videobuf2-v4l2.c.
This could be also changed later on if needed, but please use struct
timespec in new APIs instead of struct timeval. V4L2 events use it, for
instance.
