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.

Alexandru Tachici (3):
  hwmon: ltc2992: Add support
  hwmon: ltc2992: Add support for GPIOs.
  dt-binding: hwmon: Add documentation for ltc2992

Changelog v1 -> v2:
- ltc2992_read_reg function returns the reg value directly
- historical min max values are reported now through lowest and highest sysfs
- added alarm sysfs for both min and max values
- added reset history option: writing to in_reset_history will reset all
lowest/highest values
- fixed missing static
- fixed dt bindings errors
