From ca1ce7207e53cfe69aee5002eb3795069668da53 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 5 Aug 2022 11:23:17 +0200 Subject: [PATCH] arm64: dts: qcom: sc8280xp-lenovo-thinkpad-x13s: add alternate touchpad Add support for the alternate (second-source) touchpad found on some X13s laptops. Note that alternate touchpad is kept disabled for now. The boot firmware should determine which device is actually populated and enable only the corresponding node.
