Linux kernel source tree

The current implementation does not apply changes to the crop- configuration of the sensor immediately if the sensor is in streaming state. The user has to stop and restart the stream for the changes to be applied. This can be undesirable e.g. in a calibration usecase where the user wants to see the impact of his changes in a live video stream. Under the condition that the width & height of the cropped image area does not change, the changed cropping configuration can be applied to the pixel-array immediately without disturbing the IFP. Call mt9m114_configure_pa() in mt9m114_pa_set_selection() if the sensor is in streaming state and the size of the cropping rectangle didn't change, issue a CONFIG_CHANGE to apply the changes immediately.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
