drm_crtc_helper_set_config - set a new config from userspace : CRTC to setup : user provided configuration : new mode to set : set of connectors for the new config : new framebuffer
LOCKING: Caller must hold mode config lock.
Setup a new configuration, provided by the user in , and enable it.
RETURNS: Zero. (FIXME)

LOCKING: Caller must hold mode config lock.
Try to set on . Give and its associated connectors a chance to fixup or reject the mode prior to trying to set it.
RETURNS: True if the mode was set successfully, or false otherwise.

drm_helper_connector_dpms affected connector DPMS mode
Calls the low-level connector DPMS function, then calls appropriate encoder and crtc DPMS functions as well

drm_helper_crtc_in_use - check if a given CRTC is in a mode_config : CRTC to check
LOCKING: Caller must hold mode config lock.
Walk 's DRM device's mode_config and see if it's in use.
RETURNS: True if is part of the mode_config, false otherwise.

drm_helper_disable_unused_functions - disable unused objects : DRM device
LOCKING: Caller must hold mode config lock.
If an connector or CRTC isn't part of 's mode_config, it can be disabled by calling its dpms function, which should power it off.

drm_helper_probe_single_connector_modes - get complete set of display modes : DRM device : max width for modes : max height for modes
LOCKING: Caller must hold mode config lock.
Based on 's mode_config layout, scan all the connectors and try to detect modes on them. Modes will first be added to the connector's probed_modes list, then culled (based on validity and the , parameters) and put into the normal modes list.
Intended to be used either at bootup time or when major configuration changes have occurred.
FIXME: take into account monitor limits
RETURNS: Number of modes found on .
