21 * compensate. Unfortunately these (cheap) devices also typically have quite
22 * generic DMI data, so we match on a combination of DMI data, screen resolution

443 * drm_get_panel_orientation_quirk - Check for panel orientation quirks
444 * @width: width in pixels of the panel
445 * @height: height in pixels of the panel
446 *
447 * This function checks for platform specific (e.g. DMI based) quirks
448 * providing info on panel_orientation for systems where this cannot be
449 * probed from the hard-/firm-ware. To avoid false-positive this function
450 * takes the panel resolution as argument and checks that against the
451 * resolution expected by the quirk-table entry.
452 *
453 * Note this function is also used outside of the drm-subsys, by for example
454 * the efifb code. Because of this this function gets compiled into its own
455 * kernel-module when built as a module.
456 *
457 * Returns:
458 * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
459 * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
