Thomas Zimmermann b3fdbd60d3 drm/renesas/rcar-du: Use fbdev-dma
Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports
damage handling, which is required by rcar-du. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.

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 reStructuredText 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.
