Hello,
I'm trying to upstream Designware USB3 host driver present in the Actions
Semi S900 SoC. It can successfully detect the USB hub but when any of the
USB device got plugged in, it fails with following error:
[ 4.365566] usb usb1-port1: connect-debounce failed
Full log can be found here: https://pastebin.ubuntu.com/p/PNff5fZkn6/

After going through the mailing list looking for similar issue, found that
some host controllers works with following quirk:
snps,dis_u3_susphy_quirk;
I tried that also but it didn't work. Can anyone shed some light on this?
PS: USB3 is working fine with vendor kernel 3.10.
Thanks,

Check what's different between mainline and your v3.10 code. Specially
look for changes in xhci and usbcore.
Good luck

This kind of error usually happen when the PHY is not working correctly.
I would check that all USB analog power supplies are enabled, PHY is
clocked and powered ON.
Good luck!
