The main binary for the pipeline on BYT/ISP2400 has its ia_css_binary_info.pipeline.left_cropping and .top_cropping fields set to 12. So a minimum padding of 12 is required. And for certain bayer-orders additional width / height padding is necessary so that the ISP crop rectangle for the raw sensor data can be used to change the bayer-order to the fixed bayer-order supported by the debayer block. Without the minmum required padding ia_css_ifmtr_configure() will fail inside ifmtr_input_start_line() and/or ifmtr_start_column() because it cannot set the ISP crop rectangle for the raw sensor data. Fix this by making atomisp_get_padding() take the minimum padding requirements into account on BYT/ISP2400 (CHT/ISP2401 does not seem to need this).

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 Restructured Text 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.
