Now all DT patches have at least a reviewed-by tag from Rob or Krzysztof, all the driver patches have one from Dmitry. Full details follow. 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 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: move tegra210_csi_soc to C file 11. staging: media: tegra-video: remove unneeded include * Preparation to make the VI module generic enough to host Tegra20 and VIP 12. staging: media: tegra-video: Kconfig: allow TPG only on Tegra210 13. staging: media: tegra-video: move tegra_channel_fmt_align to a per-soc op 14. staging: media: tegra-video: move default format to soc-specific data 15. staging: media: tegra-video: move MIPI calibration calls from VI to CSI 16. staging: media: tegra-video: add a per-soc enable/disable op 17. staging: media: tegra-video: move syncpt init/free to a per-soc op 18. staging: media: tegra-video: add syncpts for Tegra20 to struct tegra_vi 19. staging: media: tegra-video: add hooks for planar YUV and H/V flip 20. staging: media: tegra-video: add H/V flip controls * Implementation of VIP and Tegra20 21. staging: media: tegra-video: add support for Tegra20 parallel input Enjoy! Changed in RESEND,v4: - add Rob's review tag on patch 2 Changed in v4: - fixed the leftovers after the removal of 'channel@0' in DT - added review tags by Dimtry Changed in v3: - removed the 'channel@0' node from the device tree representation of vip - squashed the last two patches (VIP + T20) into one - small cleanups - rebase on v6.2-rc1 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 [v4] https://lore.kernel.org/linux-tegra/20230130141603.323221-1-luca.ceresoli@bootlin.com/ [v3] https://lore.kernel.org/linux-media/20221229133205.981397-1-luca.ceresoli@bootlin.com/ [v2] https://lore.kernel.org/linux-tegra/20221222100328.6e341874@booty/T/#t [v1] https://lore.kernel.org/linux-tegra/20221124155634.5bc2a423@booty/T/#t Luca Luca Ceresoli (21): dt-bindings: display: tegra: add Tegra20 VIP dt-bindings: display: tegra: vi: add 'vip' property and example staging: media: tegra-video: fix .vidioc_enum_fmt_vid_cap to return all formats staging: media: tegra-video: improve documentation of tegra_video_format fields staging: media: tegra-video: document tegra_channel_get_remote_source_subdev staging: media: tegra-video: fix typos in comment staging: media: tegra-video: improve error messages staging: media: tegra-video: slightly simplify cleanup on errors staging: media: tegra-video: move private struct declaration to C file staging: media: tegra-video: move tegra210_csi_soc to C file staging: media: tegra-video: remove unneeded include staging: media: tegra-video: Kconfig: allow TPG only on Tegra210 staging: media: tegra-video: move tegra_channel_fmt_align to a per-soc op staging: media: tegra-video: move default format to soc-specific data staging: media: tegra-video: move MIPI calibration calls from VI to CSI staging: media: tegra-video: add a per-soc enable/disable op staging: media: tegra-video: move syncpt init/free to a per-soc op staging: media: tegra-video: add syncpts for Tegra20 to struct tegra_vi staging: media: tegra-video: add hooks for planar YUV and H/V flip staging: media: tegra-video: add H/V flip controls staging: media: tegra-video: add support for Tegra20 parallel input .../display/tegra/nvidia,tegra20-vi.yaml | 59 ++ .../display/tegra/nvidia,tegra20-vip.yaml | 41 ++ MAINTAINERS | 3 + drivers/staging/media/tegra-video/Kconfig | 1 + drivers/staging/media/tegra-video/Makefile | 2 + drivers/staging/media/tegra-video/csi.c | 48 ++ drivers/staging/media/tegra-video/csi.h | 4 - drivers/staging/media/tegra-video/tegra20.c | 661 ++++++++++++++++++ drivers/staging/media/tegra-video/tegra210.c | 97 ++- drivers/staging/media/tegra-video/vi.c | 321 ++------- drivers/staging/media/tegra-video/vi.h | 75 +- drivers/staging/media/tegra-video/video.c | 5 + drivers/staging/media/tegra-video/video.h | 2 +- drivers/staging/media/tegra-video/vip.c | 290 ++++++++ drivers/staging/media/tegra-video/vip.h | 68 ++ 15 files changed, 1387 insertions(+), 290 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/tegra/nvidia,tegra20-vip.yaml create mode 100644 drivers/staging/media/tegra-video/tegra20.c create mode 100644 drivers/staging/media/tegra-video/vip.c create mode 100644 drivers/staging/media/tegra-video/vip.h -- 2.34.1
