+ requests which have been issued to userspace are requeued and will be

+ ``UBLK_F_USER_RECOVERY_REISSUE`` is designed for backends who tolerate

Pipelines and media streams
^^^^^^^^^^^^^^^^^^^^^^^^^^^
+A media stream is a stream of pixels or metadata originating from one or more
+source devices (such as a sensors) and flowing through media entity pads
+towards the final sinks. The stream can be modified on the route by the
+devices (e.g. scaling or pixel format conversions), or it can be split into
+multiple branches, or multiple branches can be merged.
+
+A media pipeline is a set of media streams which are interdependent. This
+interdependency can be caused by the hardware (e.g. configuration of a second
+stream cannot be changed if the first stream has been enabled) or by the driver
+due to the software design. Most commonly a media pipeline consists of a single
+stream which does not branch.
+
When starting streaming, drivers must notify all entities in the pipeline to
prevent link states from being modified during streaming by calling
:c:func:`media_pipeline_start()`.
-The function will mark all entities connected to the given entity through
-enabled links, either directly or indirectly, as streaming.
+The function will mark all the pads which are part of the pipeline as streaming.
The struct media_pipeline instance pointed to by
-the pipe argument will be stored in every entity in the pipeline.
+the pipe argument will be stored in every pad in the pipeline.
Drivers should embed the struct media_pipeline
in higher-level pipeline structures and can then access the
-pipeline through the struct media_entity
+pipeline through the struct media_pad
pipe field.
Calls to :c:func:`media_pipeline_start()` can be nested.

+
+The sensor drivers use of v4l2_get_subdev_hostdata(), which returns
+a camera_mipi_info struct. This struct is allocated/managed by
+the core atomisp code. The most important parts of the struct
+are filled by the atomisp core itself, like e.g. the port number.
+
+The sensor drivers on a set_fmt call do fill in camera_mipi_info.data
+which is a atomisp_sensor_mode_data struct. This gets filled from
+a function called <sensor_name>_get_intg_factor(). This struct is not
+used by the atomisp code at all. It is returned to userspace by
+a ATOMISP_IOC_G_SENSOR_MODE_DATA and the Android userspace does use this.
+
+Other members of camera_mipi_info which are set by some drivers are:
+-metadata_width, metadata_height, metadata_effective_width, set by
+ the ov5693 driver (and used by the atomisp core)
+-raw_bayer_order, adjusted by the ov2680 driver when flipping since
+ flipping can change the bayer order
