Add flash/strobe support for ov9282
|
expand
|
This series adds basic flash/strobe support for ov9282 sensors using their "hardware strobe output". Apart from en-/disabling the flash/strobe output, setting a timeout (duration of activated strobe per frame) is implemented. The calculation of this timeout is only interpolated from various measurements, as no documentation was found. Further flash/strobe-related controls as well as a migration to v4l2-cci helpers will likely be implemented in future series. All register addresses/values are based on the OV9281 datasheet v1.53 (january 2019). This series was tested using an ov9281 VisionComponents camera module.
