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. Signed-off-by: Alexandru Tachici <alexandru.tachici@analog.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

-----------
|
||
|
||
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.
