| Description |
| ----------- |
| |
| This driver implements initial support for the NXP MC34VR500 PMIC. The MC34VR500 |
| monitors the temperature, input voltage and output currents and provides |
| corresponding alarms. For the temperature, the chip can send interrupts if |
| the temperature rises above one of the following values: 110°, 120°, 125° and |
| 130° Celsius. For the input voltage, an interrupt is sent when the voltage |
| drops below 2.8V. |
| |
| Currently, this driver only implements the input voltage and temperature |
| alarms. The interrupts are mapped as follows: |
| |
| <= 2.8V -> in0_min_alarm |
| >110°c -> temp1_max_alarm |
| >120°c -> temp1_crit_alarm |
| >130°c -> temp1_emergency_alarm |
