Enable HDCP 1.4 DP MST stream encryption. Enable stream encryption once encryption is enabled on the DP transport driving the link for each stream which has requested encryption. Disable stream encryption for each stream that no longer requires encryption before disabling HDCP encryption on the link. v2: - Added debug print for stream encryption. - Disable the hdcp on port after disabling last stream encryption. v3: - Cosmetic change, removed the value less comment. [Uma] v4: - Split the Gen12 HDCP enablement patch. [Ram] - Add connector details in drm_err. v5: - uniformity for connector detail in DMESG. [Ram] - comments improvement.

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.
