12description:
13 NVIDIA VRS-10 (Voltage Regulator Specification) is a Power Management IC
14 (PMIC) that implements a power sequencing solution with I2C interface.
15 The device includes a real-time clock (RTC) with 32kHz clock output and
16 backup battery support, alarm functionality for system wake-up from
17 suspend and shutdown states, OTP memory for power sequencing configuration,
18 and an interrupt controller for managing VRS events.
