[libcamera-devel] [PATCH v2 00/13] libcamera: pipeline: rkisp1: Extend to support two streams

[Niklas Söderlund]

Hi,

This series extends the RkISP1 pipeline handler to work with 2 streams.
It allows cameras backed by this pipeline to expose a main path stream,
same as the one before this series. And a new self path stream that can
operate in addition or independently from the main path.

The self path supports two new RGB formats that is not supported by the
main path. This series does not extend support for RAW formats as this
is such a special case for this pipeline. Only the main path may be
active and no ISP parameters can be processed. This may be added on top
but functionality have been proven as a prototype.

To be able to use both main and self path simultaneously must run a
kernel that includes [1]. The development of the series is tested on the
media-tree [2] with out-of-tree DTS patches for the test Scarlet 
platform to enable the camera sensors.
