+Description:
+ Some regulator directories will contain a field called
+ bypass. This indicates if the device is in bypass mode.
+
+ This will be one of the following strings:
+
+ 'enabled'
+ 'disabled'
+ 'unknown'
+
+ 'enabled' means the regulator is in bypass mode.
+
+ 'disabled' means that the regulator is regulating.
+
+ 'unknown' means software cannot determine the state, or
+ the reported state is invalid.
