Complex unsigned 8-bit IQ sample


Description
===========

This format contains sequence of complex number samples. Each complex
number consist two parts, called In-phase and Quadrature (IQ). Both I
and Q are represented as a 8 bit unsigned number. I value comes first
and Q value after that.

**Byte Order.**
Each cell is one byte.

doc-rst: v4l/pixfmt: re-join a broken paragraph Originally, at the DocBook, the "Byte Order" were a single paragraph with the string that follows it. The conversion broke it, and, sometimes, it added an extra dot. Fix them altogheter at pixfmt-*.
