475  * @width: width in pixels of the panel
476  * @height: height in pixels of the panel
477  *
478  * This function checks for platform specific (e.g. DMI based) quirks
479  * providing info on panel_orientation for systems where this cannot be
480  * probed from the hard-/firm-ware. To avoid false-positive this function
481  * takes the panel resolution as argument and checks that against the
482  * resolution expected by the quirk-table entry.
483  *
484  * Note this function is also used outside of the drm-subsys, by for example
485  * the efifb code. Because of this this function gets compiled into its own
486  * kernel-module when built as a module.
487  *
488  * Returns:
489  * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
490  * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
