Ramalingam C 5e23491175 misc/mei/hdcp: Enabling the HDCP authentication
Request to ME to configure a port as authenticated.

On Success, ME FW will mark the port as authenticated and provides
HDCP cipher with the encryption keys.

Enabling the Authentication can be requested once all stages of
HDCP2.2 authentication is completed by interacting with ME FW.

Only after this stage, driver can enable the HDCP encryption for
the port, through HW registers.

README

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.
