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 board? :)

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

regards Frank

i noticed that upper usb-Port (otg) is broken on my Bananapi R2Pro with 5.19-rc1, works with 5.18.0

this port is a usb3 (xhci) port which includes an usb2-phy and should support otg, but i still want
to use it in host-only mode (USB-A socket).

already tried setting dr_mode in dts back to "host" as this was changed in rk356x.dtsi by this commit:

bc405bb3eeee 2022-04-25 arm64: dts: rockchip: enable otg/drd operation of usb_host0_xhci in rk356x

i see no error in dmesg and usb-controllers seem to be initialized completely (visible in lsusb).

r2pro has ID-Pin not connected, so i tried also peters Patch without success :(
