346 * The child device config, aka the display device data structure, provides a
347 * description of a port and its configuration on the platform.
349 * The child device config size has been increased, and fields have been added
350 * and their meaning has changed over time. Care must be taken when accessing
351 * basically any of the fields to ensure the correct interpretation for the BDB
352 * version in question.
354 * When we copy the child device configs to dev_priv->vbt.child_dev, we reserve
355 * space for the full structure below, and initialize the tail not actually
356 * present in VBT to zeros. Accessing those fields is fine, as long as the
357 * default zero is taken into account, again according to the BDB version.
359 * BDB versions 155 and below are considered legacy, and version 155 seems to be
360 * a baseline for some of the VBT documentation. When adding new fields, please
361 * include the BDB version when the field was added, if it's above that.
