From 070e2b7b7c3ef6e640e13aeb120c958e09accbb1 Mon Sep 17 00:00:00 2001 From: Philippe Schenker Date: Wed, 2 Nov 2022 14:25:56 +0100 Subject: [PATCH 3/4] drivers: chipidea: disable runtime-pm for imx6ul Colibri iMX6ULL does not properly work with runtime-pm enabled. We see two issues with that enabled: 1. Runtime PM disconnects the line as it thinks there is no VBUS - because this signal is not hooked up in hardware. The driver gets a wakeup signal from the attached hub after about 2s which leads to a reset loop. 2. In Dual-Role switching mode usb-device is not detected when plugged in. The reason was never fully understood.
