description:
  NVIDIA VRS-10 (Voltage Regulator Specification) is a Power Management IC
  (PMIC) that implements a power sequencing solution with I2C interface.
  The device includes a real-time clock (RTC) with 32kHz clock output and
  backup battery support, alarm functionality for system wake-up from
  suspend and shutdown states, OTP memory for power sequencing configuration,
  and an interrupt controller for managing VRS events.
