+/* WARNING!
+ * NCT668XD is a "new generation" SuperIO, which implements parts of its
+ * functionality in firmware. That means one should check if the desired
+ * function/register is mentioned in the EC Space datasheet before trying
+ * to modify any registers in HW.
+ * Both datasheets (HW and EC Space) are available on request from Nuvoton.
+ *
+ * These are the warnings from the datasheet:
+ * 1. All GPIO pin functions should always be customized by firmware. BIOS /
+ *    Driver should not touch all configuration registers here and related IO
+ *    ports unless firmware opens them.
+ * 2. Under any situations, CR30h should always be controlled by EC and never
+ *    be opened for BIOS / Drivers !!
+ * 3. Some GPIO pin functions were configured when related SW functions of EC
+ *    Space were enabled. For such situations BIOS or application programs
+ *    should not alter these setting to avoid abnormal function of underlying
+ *    firmware. Please refer to EC Space Specification before going to change
+ *    any configuration setting of GPIO pins.
