That attribute used to be obtained from platform data by a soc_camera
host interface and passed to the sensor driver for .s_mbus_fmt() video
operation callback, later reused as .set_fmt() pad operation callback,
to be able to limit frame rate. The driver stored that value in its
private structure for further use from .g/s_parm(), later converted to
g/s_frame_interval().
On conversion of the driver from soc_camera sensor to a standalone V4L2
subdevice by commit 23a52386fa ("media: ov6650: convert to standalone
v4l2 subdevice"), that attribute had been replaced by a constant and
hardcoded to an arbitrarily chosen pixel clock limit. Drop it. Host
interfaces can limit frame rate if needed by calling
.s_frame_interval().

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.
