+Description
+-----------
+
+This driver supports hardware monitoring for Linear Technology LTC2992 power monitor.
+
+LTC2992 is a rail-to-rail system monitor that measures current,
+voltage, and power of two supplies.
+
+Two ADCs simultaneously measure each supply's current. A third ADC monitors
+the input voltages and four auxiliary external voltages.
+
+
+Sysfs entries

+
+The following attributes are supported. Limits are read-write,
+all other attributes are read-only.
+
+in_reset_history	Reset all highest/lowest values.
+
+inX_input		Measured voltage.
+inX_lowest		Minimum measured voltage.
+inX_highest		Maximum measured voltage.
+inX_min			Minimum voltage allowed.
+inX_max			Maximum voltage allowed.
+inX_min_alarm		An undervoltage occurred. Cleared on read.
+inX_max_alarm		An overvoltage occurred. Cleared on read.
