the patch looks okay, but it didn't get USB working after applying your 
patch in combination with my patch.

devm_phy_get(hsotg->dev, "usb2-phy") failed, but ret has a value of -38. 
I don't know where this strange value comes from.

I also experience issues with my rootfs, so i think could be a problem 
with my build or the linux-next version. Tomorrow i will try the patches 
on top of Felipe's repo.

Thanks
Stefan
