* it can display. For example, a given display pipe may be responsible
* to set a clock value. If the clock can not produce all the values
* for the available modes then this callback can be used to restrict
* the number of modes to only the ones that can be displayed. Another
* reason can be bandwidth mitigation: the memory port on the display
* controller can have bandwidth limitations not allowing pixel data
* to be fetched at any rate.
*
* This hook is used by the probe helpers to filter the mode list in
* drm_helper_probe_single_connector_modes(), and it is used by the
* atomic helpers to validate modes supplied by userspace in
* drm_atomic_helper_check_modeset().
