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.
