This patch series adds support for NVIDIA's Voltage Regulator Specification
(VRS) Power Sequencer (PSEQ) controller. This controller includes a PSEQ
hardware block, that manages power sequencing and voltage regulation for
various components in the system. This controller also provides 32kHz RTC
support with backup battery for system timing.

The series includes:
- Device tree bindings for the VRS PSEQ controller
- MFD driver to handle the core functionality
- RTC driver for the PSEQ's real-time clock functionality
- Device tree nodes for Tegra234 platforms
- Configuration updates to enable the driver

Shubhi Garg (5):
  dt-bindings: mfd: add bindings for NVIDIA VRS PSEQ
  arm64: tegra: Add device-tree node for NVVRS PSEQ
  mfd: nvvrs: add NVVRS PSEQ MFD driver
  rtc: nvvrs: add NVIDIA VRS PSEQ RTC device driver
  arm64: defconfig: enable NVIDIA VRS PSEQ
