+10-bit Bayer formats
+
+Description
+===========
+
+These four pixel formats are used by Intel IPU3 driver, they are raw
+sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
+to 32 bytes leaving 6 most significant bits padding in the last byte.
+The format is little endian.
+
+In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
+Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
+
+**Byte Order.**
+Each cell is one byte.
