    <para>This format is similar to <link
linkend="V4L2-PIX-FMT-SBGGR8">
<constant>V4L2_PIX_FMT_SBGGR8</constant></link>, except each pixel has
a depth of 16 bits. The least significant byte is stored at lower
memory addresses (little-endian). Note the actual sampling precision
may be lower than 16 bits, for example 10 bits per pixel with values
in range 0 to 1023.</para>
