The simple display pipeline is a set of helpers that can be used by DRM drivers to avoid dealing with all the needed components and just define a few functions to operate a simple display device with one full-screen scanout buffer feeding a single output. But it is arguable that this provides the correct level of abstraction for simple drivers, and recently some have been ported from using these simple display helpers to use the regular atomic helpers instead. The rationale for this is that the simple display pipeline helpers don't hide that much of the DRM complexity, while adding an indirection layer that conflates the concepts of CRTCs and planes. This makes the helpers less flexible and harder to be reused among different graphics drivers. Also, for simple drivers, using the full atomic helpers doesn't require a lot of additional code. So adding a simple display pipeline layer may not be worth it. For these reasons, let's follow that trend and make ssd130x a plain DRM driver that creates its own primary plane, CRTC, enconder and connector.

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.
