This patch adds auto control mode debugfs CRC support based on DPU Signature units. The evaluation window is the same to the display region as indicated by drm_crtc_state->adjusted_mode. The CRC data count is three when single DPU display stream is used, while six when the pixel combiner(dual DPU display streams) is used. Each data shows the CRC value for the 8 most significant bits of red/green/blue channel of the entire evaluation window, which reflects how DPU Signature unit reports CRC values.

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.
