media: cec: include linux/debugfs.h and linux/seq_file.h where needed

2025-01-07T11:21:38Z

Having cec.h include linux/debugfs.h leads to all users of all cec headers include and depend on debugfs.h and its dependencies for no reason. Drop the include from cec.h, and include debugfs.h and seq_file.h where needed. Sort all the modified include lists while at it. Signed-off-by: Jani Nikula Signed-off-by: Hans Verkuil

media: v4l2-core: v4l2-dv-timings: check cvt/gtf result

2024-10-28T14:35:56Z

The v4l2_detect_cvt/gtf functions should check the result against the timing capabilities: these functions calculate the timings, so if they are out of bounds, they should be rejected. To do this, add the struct v4l2_dv_timings_cap as argument to those functions. This required updates to the adv7604 and adv7842 drivers since the prototype of these functions has now changed. The timings struct that is passed to v4l2_detect_cvt/gtf in those two drivers is filled with the timings detected by the hardware. The vivid driver was also updated, but an additional check was added: the width and height specified by VIDIOC_S_DV_TIMINGS has to match the calculated result, otherwise something went wrong. Note that vivid *emulates* hardware, so all the values passed to the v4l2_detect_cvt/gtf functions came from the timings struct that was filled by userspace and passed on to the driver via VIDIOC_S_DV_TIMINGS. So these fields can contain random data. Both the constraints check via struct v4l2_dv_timings_cap and the additional width/height check ensure that the resulting timings are sane and not messed up by the v4l2_detect_cvt/gtf calculations.

2024-10-12T08:44:05Z

Add new helpers to export received or transmitted HDMI InfoFrames to debugfs. This complements similar code in drm where the transmitted HDMI infoframes are exported to debugfs. The same names have been used as in drm, so this is consistent. The exported infoframes can be parsed with the edid-decode utility. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
