drm_atomic_helper_resume — subsystem-level resume helper
int drm_atomic_helper_resume ( | struct drm_device * dev, |
struct drm_atomic_state * state) ; |
Calls drm_mode_config_reset
to synchronize hardware and software states,
grabs all modeset locks and commits the atomic state object. This can be
used in conjunction with the drm_atomic_helper_suspend
helper to
implement suspend/resume for drivers that support atomic mode-setting.
