+         SmartReflex can perform continuous dynamic voltage
+         scaling around the nominal operating point voltage
+         according to silicon characteristics and operating
+         conditions. Enabling SmartReflex reduces power
+         consumption.
+
+         Please note, that by default SmartReflex is only
+         initialized. To enable the automatic voltage
+         compensation for VDD1 and VDD2, user must write 1 to
+         /sys/power/sr_vddX_autocomp, where X is 1 or 2.

+         In some devices the E-fuse values have not been set, even though
+         SmartReflex modules are included. Using these hardcoded values set
+         in software, one can test the SmartReflex features without E-fuse.
