410  * @width: width in pixels of the panel
411  * @height: height in pixels of the panel
412  *
413  * This function checks for platform specific (e.g. DMI based) quirks
414  * providing info on panel_orientation for systems where this cannot be
415  * probed from the hard-/firm-ware. To avoid false-positive this function
416  * takes the panel resolution as argument and checks that against the
417  * resolution expected by the quirk-table entry.
418  *
419  * Note this function is also used outside of the drm-subsys, by for example
420  * the efifb code. Because of this this function gets compiled into its own
421  * kernel-module when built as a module.
422  *
423  * Returns:
424  * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
425  * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
