The CLK_POL field specifies whether data is sampled on the falling or
rising edge of PCLK, not whether the data lines are active high or low.
Evidence of this can be found in the timing diagram labeled "horizontal
size setting and pixel clock timing".
Fix the setting by checking the correct flag, V4L2_MBUS_PCLK_SAMPLE_RISING.
While at it, reorder the three polarity flag checks so HSYNC and VSYNC
are grouped together.

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.
