+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.
+
+Upstream-Status: Inappropriate [Configuration for colibri-imx6ull]
