Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2022-10-22T22:30:15Z

Pull missed media updates from Mauro Carvalho Chehab: "It seems I screwed-up my previous pull request: it ends up that only half of the media patches that were in linux-next got merged in -rc1. The script which creates the signed tags silently failed due to 5.19->6.0 so it ended generating a tag with incomplete stuff. So here are the missing parts: - a DVB core security fix - lots of fixes and cleanups for atomisp staging driver - old drivers that are VB1 are being moved to staging to be deprecated - several driver updates - mostly for embedded systems, but there are also some things addressing issues with some PC webcams, in the UVC video driver" * tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (163 commits) media: sun6i-csi: Move csi buffer definition to main header file media: sun6i-csi: Introduce and use video helper functions media: sun6i-csi: Add media ops with link notify callback media: sun6i-csi: Remove controls handler from the driver media: sun6i-csi: Register the media device after creation media: sun6i-csi: Pass and store csi device directly in video code media: sun6i-csi: Tidy up video code media: sun6i-csi: Tidy up v4l2 code media: sun6i-csi: Tidy up Kconfig media: sun6i-csi: Use runtime pm for clocks and reset media: sun6i-csi: Define and use variant to get module clock rate media: sun6i-csi: Always set exclusive module clock rate media: sun6i-csi: Tidy up platform code media: sun6i-csi: Refactor main driver data structures media: sun6i-csi: Define and use driver name and (reworked) description media: cedrus: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-rotate: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-di: Add a Kconfig dependency on RESET_CONTROLLER media: sun4i-csi: Add a Kconfig dependency on RESET_CONTROLLER media: sun6i-csi: Add a Kconfig dependency on RESET_CONTROLLER ...

media: atomisp_gmin_platform: Unexport and split camera_sensor_csi()

2022-09-24T08:15:15Z

The camera_sensor_csi() is not used outside the module, hence make it static. While at it, split it to _alloc() and _free() to clearly show the idea behind the last parameter @flag that is passed to gmin_csi_cfg().

media: atomisp: Remove atomisp_source_pad_to_stream_id()

2022-09-24T08:14:39Z

atomisp_source_pad_to_stream_id() returns ATOMISP_INPUT_STREAM_GENERAL unconditionally now. Drop it and directly use ATOMISP_INPUT_STREAM_GENERAL in its callers. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

media: atomisp: Remove const/fixed camera_caps

2022-09-24T08:13:49Z

The code checks a camera_caps struct in various places, but this always points to the same const camera_caps struct. Remove the checks, keeping the code paths which would be taken with the fixed camera caps struct still in place and remove the camera_caps struct itself. Note this completely removes atomisp_pause_buffer_event() because that only ever does something if camera_caps.sensors[0].is_slave is true and that never is true.

media: atomisp: Remove unused atomisp_css_get_dis_statistics()

2022-09-24T08:12:58Z

Remove the unused atomisp_css_get_dis_statistics() function. This seems to be a leftover variant / older version of atomisp_css_get_dis_stats() which is actually used. Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

media: atomisp: Make atomisp_set_raw_buffer_bitmap() static

2022-09-24T08:12:14Z

atomisp_set_raw_buffer_bitmap() is only used in atomisp_cmd.c, make it static. Unfortunately this still requires a forward declaration (the function cannot be moved easily). Still this will at least make it obvious to anyone reading the code that the function is not used elsewhere.

media: atomisp: Drop unnecessary first_streamoff check

2022-09-24T08:11:35Z

Drop an unnecessary first_streamoff check from atomisp_streamoff(), above the check there is a: if (!first_streamoff) goto stop_sensor; Code block which will jump over the code with the test, so the test is only executed when first_streamoff is true and therefor the test is not necessary.

media: atomisp: Remove a couple of not useful function wrappers

2022-09-24T08:10:53Z

The __atomisp_reqbufs(), __atomisp_streamoff() are 1:1 wrappers for the non __ prefixed functions now, drop these wrappers. The atomisp_s_fmt_cap() wrapper is almost a 1:1 wrapper for atomisp_set_fmt() adjust the latter to have the right function prototype and drop the wrapper.

media: atomisp: Use video_dev.lock for ioctl locking
