 22 * generic DMI data, so we match on a combination of DMI data, screen resolution

494 *
495 * This function checks for platform specific (e.g. DMI based) quirks
496 * providing info on panel_orientation for systems where this cannot be
497 * probed from the hard-/firm-ware. To avoid false-positive this function
498 * takes the panel resolution as argument and checks that against the
499 * resolution expected by the quirk-table entry.
500 *
501 * Note this function is also used outside of the drm-subsys, by for example
502 * the efifb code. Because of this this function gets compiled into its own
503 * kernel-module when built as a module.
504 *
505 * Returns:
506 * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
507 * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.

377 * drm_get_panel_orientation_quirk - Check for panel orientation quirks
378 * @width: width in pixels of the panel
379 * @height: height in pixels of the panel
380 *
381 * This function checks for platform specific (e.g. DMI based) quirks
382 * providing info on panel_orientation for systems where this cannot be
383 * probed from the hard-/firm-ware. To avoid false-positive this function
384 * takes the panel resolution as argument and checks that against the
385 * resolution expected by the quirk-table entry.
386 *
387 * Note this function is also used outside of the drm-subsys, by for example
388 * the efifb code. Because of this this function gets compiled into its own
389 * kernel-module when built as a module.
390 *
391 * Returns:
392 * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
393 * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
