+Generic line-based metadata formats
+
+
+Description
+===========
+
+These generic line-based metadata formats define the memory layout of the data
+without defining the format or meaning of the metadata itself. These formats may
+only be used with a Media controller pipeline where the more specific format is
+defined in an :ref:`internal source pad <MEDIA-PAD-FL-INTERNAL>` of the source
+sub-device. See also :ref:`source routes <subdev-routing>`.
+
+.. _v4l2-meta-fmt-generic-8:
+
+V4L2_META_FMT_GENERIC_8
+-----------------------
+
+The V4L2_META_FMT_GENERIC_8 format is a plain 8-bit metadata format.
+
+This format is also used on CSI-2 for both 8 bits per ``Data unit
+<media-glossary-data-unit>`` as well as for 16 bits per Data unit when two bytes
+of metadata are packed into one 16-bit Data unit.
+
+**Byte Order Of V4L2_META_FMT_GENERIC_8.**
+Each cell is one byte. "M" denotes a byte of metadata.

+
+V4L2_META_FMT_GENERIC_CSI2_10 contains packed 8-bit generic metadata, 10 bits
+for each 8 bits of data. Every four bytes of metadata is followed by a single
+byte of padding. The way the data is packed follows the MIPI CSI-2 specification
+and the padding is defined in the MIPI CCS specification.
+
+This format is also used in conjunction with 20 bits per ``Data unit

+Data unit.
+
+This format is little endian.
+
+**Byte Order Of V4L2_META_FMT_GENERIC_CSI2_10.**
+Each cell is one byte. "M" denotes a byte of metadata and "X" a byte of padding.
