It requires to check streams type1 capability in mst topology
by checking Rxinfo instead connector HDCP2.x capability in
order to enforce type0 stream encryption in a mix of
HDCP {1.x,2.x} mst topology.
Rxcaps always shows HDCP 2.x capability of immediate downstream
connector. Let's use Rxinfo HDCP1_DEVICE_DOWNSTREAM bit to
detect a HDCP {1.x,2.x} mix mst topology.

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.
