Hi,

traced it down with manual reverts to this one:

commit 6a98df08ccd55e87947d253b19925691763e755c
    phy: rockchip-inno-usb2: Fix muxed interrupt support

luckily i can revert only this and now upper usb-port works again

@samuel: have you an idea how to fix your problem without breaking my boar=
d? :)

@greg/Vinod: maybe we can add a revert of this in mainline till issue is r=
esolved?

regards Frank
