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.
