+Kernel driver ltc2992
+=====================
+
+Supported chips:
+  * Linear Technology LTC2992
+    Prefix: 'ltc2992'
+    Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ltc2992.pdf
+
+Author: Alexandru Tachici <alexandru.tachici@analog.com>
+
+
+Description
+-----------
+
+This driver supports hardware monitoring for Linear Technology LTC2992 power monitor.
+
+LTC2992 is 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.
+
+inX_input		Measured voltage.
+inX_min			Minimum voltage.
+inX_max			Maximum voltage.
+inX_min_alarm		Voltage low alarm.
+inX_max_alarm		Voltage high alarm.
+inX_alarm		An overvoltage or undervoltage occured. Cleared on read.
+
+currX_input		Measured current.
+currX_min		Minimum current.
+currX_max		Maximum current.
+currX_min_alarm		Current low alarm.
+currX_max_alarm		Current high alarm.
+currX_alarm		An overvoltage or undervoltage occured. Cleared on read.
+
+powerX_input		Measured power.
+powerX_min		Minimum power.
+powerX_max		Maximum power.
+powerX_min_alarm	Power low alarm.
+powerX_max_alarm	Power high alarm.
+powerX_alarm		An overpower or underpower occured. Cleared on read.
