From 17372bd812dcdd7371a20e6226d2d1bbf415a47b Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 12 Mar 2020 18:45:50 -0700 Subject: hw/arm/fsl-imx6ul: Wire up USB controllers IMX6UL USB controllers are quite similar to IMX7 USB controllers. Wire them up the same way. The only real difference is that wiring up phy devices is necessary to avoid phy reset timeouts in the Linux kernel.
