+ * to access services provided by the parent driver. The structure may contain
+ * sub-struct pointers to group function pointers by functionality.

+ * All function and sub-struct pointers must be initialized and callable unless
+ * explicitly marked as "optional" below. The display driver will only NULL
+ * check the optional pointers.
