[PATCH 00/10] media: i2c: ov9282: fix control range handling
Posted by Richard Leitner 1 week, 3 days ago
This series fixes a set of related issues in the OV9282 control handling
code.

The driver updated exposure- and flash duration-related control ranges
in several places, but some of those updates used an incorrect timebase
or were triggered too late, which could leave the controls clamped
against stale values.

The series:
- checks the return value of exposure range updates,
- introduces various helpers for calculating/converting times,
- refreshes flash-duration limits while the sensor is powered down,
- refreshes dependent ranges on mode changes,
- recomputes flash-duration limits when HBLANK changes,
- removes the no longer needed hblank field of the driver struct,
- harmonizes error printing during probe

This series was tested with an ov9282 sensor on a vision components camera
module attached to an i.MX8MP mainboard.

Any feedback is warmly welcome.

Thanks!
