Subject: [PATCH v2 00/21] Add Tegra20 parallel video input capture
Date: Mon, 28 Nov 2022 16:23:15 +0100 [thread overview]
Message-ID: <20221128152336.133953-1-luca.ceresoli@bootlin.com> (raw)
Tegra20 and other Tegra SoCs have a video input (VI) peripheral that can
receive from either MIPI CSI-2 or parallel video (called respectively "CSI"
and "VIP" in the documentation). The kernel currently has a staging driver
for Tegra210 CSI capture. This patch set adds support for Tegra20 VIP
capture.
Unfortunately I had no real documentation available to base this work on.
I only had a working downstream 3.1 kernel, so I started with the driver
found there and heavily reworked it to fit into the mainline tegra-video
driver structure. The existing code appears written with the intent of
being modular and allow adding new input mechanisms and new SoCs while
keeping a unique VI core module. However its modularity and extensibility
was not enough to add Tegra20 VIP support, so I added some hooks to turn
hard-coded behaviour into per-SoC or per-bus customizable code. There are
also a fix, some generic cleanups and DT bindings.
Quick tour of the patches:
* Device tree bindings and minor DTS improvements
01. dt-bindings: display: tegra: add Tegra20 VIP
02. dt-bindings: display: tegra: vi: add 'vip' property and example
* A fix
03. staging: media: tegra-video: fix .vidioc_enum_fmt_vid_cap to return all formats
* Minor improvements to logging, comments, cleanups
04. staging: media: tegra-video: improve documentation of tegra_video_format fields
05. staging: media: tegra-video: document tegra_channel_get_remote_source_subdev
06. staging: media: tegra-video: fix typos in comment
07. staging: media: tegra-video: improve error messages
08. staging: media: tegra-video: slightly simplify cleanup on errors
09. staging: media: tegra-video: move private struct declaration to C file
10. staging: media: tegra-video: remove unneeded include
* Preparation to make the VI module generic enough to host Tegra20 and VIP
11. staging: media: tegra-video: Kconfig: allow TPG only on Tegra210
12. staging: media: tegra-video: move tegra_channel_fmt_align to a per-soc op
13. staging: media: tegra-video: move default format to soc-specific data
14. staging: media: tegra-video: move MIPI calibration calls from VI to CSI
15. staging: media: tegra-video: add a per-soc enable/disable op
16. staging: media: tegra-video: move syncpt init/free to a per-soc op
17. staging: media: tegra-video: add syncpts for Tegra20 to struct tegra_vi
18. staging: media: tegra-video: add hooks for planar YUV and H/V flip
19. staging: media: tegra-video: add H/V flip controls
* Implementation of VIP and Tegra20
20. staging: media: tegra-video: add support for VIP (parallel video input)
21. staging: media: tegra-video: add tegra20 variant
Enjoy!
Changed in v2:
- improved dt-bindings patches based on reviews
- removed patches 3 and 4 adding DT labels without a mainline user
- two small fixes to the last patch
