media: i2c: ov5647: use our own mutex for the ctrl lock

2026-03-04T12:20:28+00:00

[ Upstream commit 973e42fd5d2b397bff34f0c249014902dbf65912 ] __v4l2_ctrl_handler_setup() and __v4l2_ctrl_modify_range() contains an assertion to verify that the v4l2_ctrl_handler::lock is held, as it should only be called when the lock has already been acquired. Therefore use our own mutex for the ctrl lock, otherwise a warning will be reported.

media: i2c: ov5647: Fix PIXEL_RATE value for VGA mode

[ Upstream commit c063632b494b02e891442d10f17e37b7fcfab9b3 ] The pixel rate for VGA (640x480) mode is configured in the mode's table to be 58.333 MPix/s instead of 55 MPix/s, so fix it.

media: i2c: ov5647: Sensor should report RAW color space

[ Upstream commit 1438248c5a82c86b4e1f0311c3bb827af747a8cf ] Trial and error reveals that the minimum vblank value appears to be 24 (the OV5647 data sheet does not give any clues).

media: i2c: ov5647: Initialize subdev before controls

[ Upstream commit eee13cbccacb6d0a3120c126b8544030905b069d ] In ov5647_init_controls() we call v4l2_get_subdevdata, but it is initialized by v4l2_i2c_subdev_init() in the probe, which currently happens after init_controls(). This can result in a segfault if the error condition is hit, and we try to access i2c_client, so fix the order.

[ Upstream commit 90289b67c5c1d4c18784059b27460d292e16d208 ] The ADV7280-M may internally convert interlaced video input to progressive video. If this mode is enabled, the ADV7280-M delivers progressive video frames at the field rate of 50 fields per second (PAL) or 60 fields per second (NTSC). Fix the reported frame interval if progressive video is enabled.
