From 63fd9437ec81899fc36bb642d558378bc89aa4f9 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Tue, 1 Nov 2022 10:30:31 +0100 Subject: [PATCH] arm64: dts: imx8mm-tqma8mqml-mba8mx: Fix USB DR Using extcon USB host mode works properly on DR interface, e.g. enabling/disabling VBUS. But USB device mode is not working. Fix this by switching to usb-role-switch instead.
