- Kernel Driver Lochnagar
- =======================
- Supported systems:
- * Cirrus Logic : Lochnagar 2
- Author: Lucas A. Tanure Alves
- Description
- -----------
- Lochnagar 2 features built-in Current Monitor circuitry that allows for the
- measurement of both voltage and current on up to eight of the supply voltage
- rails provided to the minicards. The Current Monitor does not require any
- hardware modifications or external circuitry to operate.
- The current and voltage measurements are obtained through the standard register
- map interface to the Lochnagar board controller, and can therefore be monitored
- by software.
- Sysfs attributes
