[PATCH v3 4/5] hw/arm/fsl-imx6ul: Wire up USB controllers |
Date: |
Thu, 12 Mar 2020 18:45:50 -0700 |
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.

v3: Wire up USB and USB PHY controllers in separate loops
While the number of USB controllers matches the number of USB PHYs,
they are logically different.
v2: Use USB PHY emulation
