DE3.0 VI layers supports plane-global alpha channel. DE2.0 FCC block have GLOBAL_ALPHA register that can be used as alpha source for blender. Add alpha property to the DRM plane and connect it to the corresponding registers in the mixer. Do not add alpha property for V3s SOC that have DE2.0 and 2 VI planes.

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.
