Subject: [PATCH v3 5/6] arm64: defconfig: enable NVIDIA VRS PSEQ
Date: Wed, 11 Jun 2025 07:34:53 +0000	[thread overview]
Message-ID: <20250611073454.978859-6-shgarg@nvidia.com> (raw)
In-Reply-To: <20250611073454.978859-1-shgarg@nvidia.com>

Enable NVIDIA VRS (Voltage Regulator Specification) power sequencer
device modules. NVIDIA VRS PSEQ provides 32kHz RTC support with backup
battery for system timing. It controls ON/OFF and suspend/resume
power sequencing of system power rails on below NVIDIA platforms:

- NVIDIA Jetson AGX Orin Developer Kit
- NVIDIA IGX Orin Development Kit
- NVIDIA Jetson Orin NX Developer Kit
- NVIDIA Jetson Orin Nano Developer Kit

Signed-off-by: Shubhi Garg <shgarg@nvidia.com>

v3:
- no changes

v2:
- moved VRS RTC config to correct place
