V4L2 sensor drivers are expected to clip the supported exposure range based on the VBLANK configured. IMX258 wasn't doing that as register 0x350 (FRM_LENGTH_CTL) switches it to a mode where frame length tracks coarse exposure time. Disable this mode and clip the range for V4L2_CID_EXPOSURE appropriately based on V4L2_CID_VBLANK.

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.
