[PATCH 00/18] media: rcar: Streams support

[Tomi Valkeinen]

Add streams support to Renesas rcar platform driver.

The series attempts to keep compatibility with the current upstream.
However, in upstream there's some kind of custom multi-stream support
implemented to the rcar driver, which breaks at patch "media: rcar-csi2:
Simplify rcsi2_calc_mbps()".

The behavior should not change when using a single stream.

A problem with the series currently is that it has a lot of
dependencies that are not in upstream yet.

Testing is even more problematic, as the only way currently for me to
get multiple streams is by using the GMSL2 deserializer add-on board
with GMSL2 serializers. These are not supported in upstream. If someone
has the hardware and wants to test, I can share the very-WIP branch that
contains the missing pieces.
