Subject: [PATCH v8 00/36] v4l: subdev internal routing and streams
Date: Mon, 30 Aug 2021 14:00:40 +0300 [thread overview]
Message-ID: <20210830110116.488338-1-tomi.valkeinen@ideasonboard.com> (raw)
Hi,
This is v8 of the multiplexed streams series. v7 can be found from:
https://lore.kernel.org/linux-media/20210524104408.599645-1-tomi.valkeinen@ideasonboard.com/
The main change in this version is the implementation and use of
centralized active state for subdevs.
I have pushed my work branch to:
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git multistream/work-v8
which contains the patches in this series, along with subdev drivers
using multiplexed streams.
Both this series and the branch above are based on top of today's
git://linuxtv.org/media_tree.git master.
The documentation still needs improving, but I hope the docs in this
series, and the drivers in the work branch, are enough to give the
reviewers enough information to do a review.
As can be guessed from the work branch, I have been testing this series
with TI's FPDLink setup. I have also done a "backwards compatibility"
test by dropping all multiplexed streams patches from the CAL driver
(the CSI-2 RX on the TI SoC), and using the FPDLink drivers with
single-stream configuration.
