From: Alexandru Tachici <alexandru.tachici@xxxxxxxxxx> 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 (GPIOs). 1. Use hwmon to create sysfs entries for current, voltage and power of two 0V to 100V supplies. Create sysfs entries for voltage sensed on the 4 GPIO pins. 2. Expose to userspace the 4 open-drain GPIOs provided by ltc2992. 3. DT bindings for ltc2992.
