1 What:		/sys/class/regulator/.../state
6 		Some regulator directories will contain a field called
7 		state. This reports the regulator enable control, for
16 		'enabled' means the regulator output is ON and is supplying
17 		power to the system (assuming no error prevents it).
19 		'disabled' means the regulator output is OFF and is not
20 		supplying power to the system (unless some non-Linux
21 		control has enabled it).

57 		regulator operation modes (described elsewhere).  They
60 		Note that regulator status is a function of many inputs,
61 		not limited to control inputs from Linux.  For example,
