- * We used to keep this struct but without any version control. We should avoid

+ * The child device config, aka the display device data structure, provides a
+ * description of a port and its configuration on the platform.
+ *
+ * The child device config size has been increased, and fields have been added
+ * and their meaning has changed over time. Care must be taken when accessing

+ *
+ * When we copy the child device configs to dev_priv->vbt.child_dev, we reserve

+ * present in VBT to zeros. Accessing those fields is fine, as long as the
+ * default zero is taken into account, again according to the BDB version.
+ *
+ * BDB versions 155 and below are considered legacy, and version 155 seems to be
+ * a baseline for some of the VBT documentation. When adding new fields, please
+ * include the BDB version when the field was added, if it's above that.
