+Kernel driver ltc2992
+=====================
+
+Supported chips:
+ * Linear Technology LTC2992
+ Prefix: 'ltc2992'

+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.
+
+currX_input Measured current.
+currX_lowest Minimum measured current.
+currX_highest Maximum measured current.
+currX_min Minimum current allowed.
+currX_max Maximum current allowed.
+currX_min_alarm An undercurrent occurred. Cleared on read.
+currX_max_alarm An overcurrent occurred. Cleared on read.
+
