Merge tag 'v6.1-rc2' into fixes

Merge rc2 into our fixes branch, which was based on rc1 but wasn't
merged until rc3, so that for the remainder of the release our fixes
branch will be based on rc2 for the purposes of resolving conflicts with
other trees (if necessary).

 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.
