- 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 <[email protected]>
- 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.
