From 707181264badf4f82c78c18348684cd06db31ce0 Mon Sep 17 00:00:00 2001 From: Igor Belwon Date: Thu, 10 Jul 2025 18:50:07 +0200 Subject: [PATCH] arm64: dts: exynos990-x1s-common: Enable USB The x1s family uses a shared USB configuration. Enable both the USB PHY as well as the DWC3 controller. Since we do not have any PMIC for USB implemented yet, use dummy regulators until we do.
