From: Svyatoslav Ryhel Date: Mon, 11 May 2026 07:48:51 +0000 (+0300) Subject: ARM: tegra: lg-x3: Complete video device graph X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8399055d9f98e94c33608fe9d61afc09a43cc4df;p=thirdparty%2Fkernel%2Flinux.git ARM: tegra: lg-x3: Complete video device graph 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.
