Subject: [PATCH v3 2/6] arm64: tegra: Add device-tree node for NVVRS PSEQ
Date: Wed, 11 Jun 2025 07:34:50 +0000 [thread overview]
Message-ID: <20250611073454.978859-3-shgarg@nvidia.com> (raw)
In-Reply-To: <20250611073454.978859-1-shgarg@nvidia.com>
Add NVIDIA VRS Power Sequencer device tree node for Tegra234 P3701 and
P3767 platforms. Assign VRS RTC as primary RTC (rtc0).
Signed-off-by: Shubhi Garg <shgarg@nvidia.com>
---
v3:
- fixed device tree node name to generic "pmic@3c"
v2:
- added alias to assign VRS RTC to rtc0
- removed status node from VRS DTB node
