[PATCH v2 00/25] drivers: media: imx283 improvements

[Kieran Bingham]

This now far more extensive series reposts some patches which provide
fixes to the users of the IMX283 camera sensor to resolve handling
exposure and blanking updates and the reporting of the cropping modes
configured.

The series then goes on to extensively extend the driver to move towards
a dedicated scan out structure allowing mode definitions to be greatly
simplified and factor out a lot of common definitions and duplication.

Vertical offset corrections are added which handle the correct
alignment of the output mode in the different binning combinations which
otherwise translate to an offset in the image capture which is
detectable when the camera is used as a measurement device.

To make use of this, the horizontal and vertical configuration is
refactored to make it clearer what calculations are being performed and
manage the vertical positioning based on the VOB and binning offsets
accordingly.

This then provides us with a mechanism to fix a separate issue that
occurs on the IMX283 where an 'extra black line' is inserted by the
sensor to resolve bayer re-ordering. This extra line is undesirable in
the output and so we account for this and remove it by instead
requesting *two* additional lines, and moving two lines back into the
VOB data type. The extra line is required to maintain bayer order, and
moving the lines prevents them from being added to the captured image.

Extra modes are added based on this new simplified mode configuration
structure to match the diagrams present in the sensor datasheet.
