In the current code, exynos_drm_suspend() function is called after all real devices (CRTCs, Encoders, etc) are suspended, because Exynos DRM virtual platform device is created as last device in the system (as a part of DRM registration). None of the devices for real hardware modules has its own system suspend/resume callbacks, so it doesn't change any order of the executed code, but it has a side-effect: runtime PM callbacks for real devices are not executed, because those devices are considered by PM core as already suspended. This might cause issues on boards with complex pipelines, where something depends on the runtime PM state of the given device. To ensure that exynos_drm_suspend() is called before any suspend callback from the real devices, assign it to .prepare callback. Same for exynos_drm_resume(), using .complete callback ensures that all real devices have been resumed when calling it.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
