media: v4l2-core: Introduce v4l2_query_ext_ctrl_to_v4l2_queryctrl

2025-03-05T09:43:26Z

We use this logic in a couple of places. Refactor into a function. No functional change expected from this patch. Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: Remove vidioc_s_ctrl callback

2025-03-05T09:43:26Z

All the drivers either use the control framework or provide a vidiod_ext_ctrl. We can remove this callback. Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: Remove vidioc_g_ctrl callback

2025-03-05T09:43:26Z

All the drivers either use the control framework or provide a vidioc_g_ext_ctrls callback. We can remove this callback. Thanks for your service! Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: Remove vidioc_queryctrl callback

2025-03-05T09:43:25Z

All the drivers either use the control framework or provide a vidioc_query_ext_ctrl. We can remove this callback to reduce the temptation of new drivers to implement it. Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: rc: reduce useless padding in struct rc_dev etc

2025-03-04T14:56:11Z

Reorder the fields in these structs so that we waste less space due to padding. pahole shows that lirc_fh is 8 bytes smaller, and rc_dev is 32 bytes smaller. Signed-off-by: Sean Young Signed-off-by: Hans Verkuil

media: v4l2-ctrls: add support for V4L2_CTRL_WHICH_MIN/MAX_VAL

2025-03-03T17:23:35Z

Add the capability of retrieving the min and max values of a compound control.

media: tuners: Constify struct tunertype, tuner_range and tuner_params

2025-02-21T09:33:15Z

'struct tunertype', 'struct tuner_range' and 'struct tuner_params' are not modified in this driver. Constifying these structures moves some data to a read-only section, so increase overall security.

media: v4l2-dv-timings: add v4l2_num_edid_blocks() helper

2025-02-18T07:11:37Z

This new function determines how many blocks the EDID has. Traditionally the number of extension blocks is read from the EDID at offset 126, but this can be overridden by the HDMI Forum EDID Extension Override Data Block. So check that as well in this helper. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l: Memset argument to 0 before calling get_mbus_config pad op

2025-02-15T14:22:54Z

Memset the config argument to get_mbus_config V4L2 sub-device pad operation to zero before calling the operation. This ensures the callers don't need to bother with it nor the implementations need to set all fields that may not be relevant to them.
