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.
