Subject: [PATCH v1 1/9] ARM: tegra: lg-x3: Complete video device graph
Date: Mon, 6 Apr 2026 11:33:56 +0300 [thread overview]
Message-ID: <20260406083404.31359-2-clamor95@gmail.com> (raw)
In-Reply-To: <20260406083404.31359-1-clamor95@gmail.com>
Add front and rear camera nodes and interlink them with Tegra CSI and VI.
Adjust camera PMIC voltages to better fit requirements and fix the focuser
node.
