| description: |
| P1 is an I2C-controlled PMIC produced by SpacemiT. It implements six |
| constant-on-time buck converters and twelve low-dropout regulators. |
| It also contains a load switch, watchdog timer, real-time clock, eight |
| 12-bit ADC channels, and six GPIOs. Additional details are available |
| in the "Power Stone/P1" section at the following link. |
