From bb787e58ef620c850ba6aebf7d477df6e376670a Mon Sep 17 00:00:00 2001 From: Frieder Schrempf Date: Mon, 20 Oct 2025 15:21:51 +0200 Subject: [PATCH] arm64: dts: imx8mp-kontron: Fix USB OTG role switching [ Upstream commit 6504297872c7a5d0d06247970d32940eba26b8b3 ] The VBUS supply regulator is currently assigned to the PHY node. This causes the VBUS to be always on, even when the controller needs to be switched to peripheral mode. Fix the OTG role switching by adding a connector node and moving the VBUS supply regulator to that node. This way the VBUS gets correctly switched according to the current role.
