- FIXME: How should set_config interact with DPMS? If the CRTC is
- suspended, should it be resumed?
+ Note that the drm core has no notion of restoring the mode setting
+ state after resume, since all resume handling is in the full
+ responsibility of the driver. The common mode setting helper library
+ though provides a helper which can be used for this:
+ <function>drm_helper_resume_force_mode</function>.
