From 4da515eca1b8de56c9e8a17866626f99d9bccbc7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Duje=20Mihanovi=C4=87?= Date: Thu, 9 Apr 2026 23:17:24 +0200 Subject: [PATCH] arm64: dts: marvell: samsung-coreprimevelte: Increase touchscreen voltage MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The old 1.9V setting was found to be insufficient in certain environments (in my case cold ones), causing the touchscreen to register ghost touches and mostly ignore actual touches. Increase the voltage to 2.5V to correct the issue.
