Hi all, this short series addresses two issues. The first issue is devices not enumerating when connected to an Odroid XU4, to its 3.0 root hub. The interplay between refactoring certain parts of dwc3's code and handling the SUSPHY quirk results in the said problem. Please see: https://patchwork.kernel.org/patch/9535235/ Actually using the quirk solves it. The second issue is devices not enumerating and/or wrongly enumerating as high speed instead of super speed on an Odroid XU3. There was a patch series from Vivek Gautam in circulation, but it got lost somehow. Please see: https://lkml.org/lkml/2014/9/2/166 https://lkml.org/lkml/2015/2/2/257 I adapted his patch so that it does not use a hacky solution to force additional initialization in order for calibration to happen. Instead I used the .reset() in phy_ops. I could have used the .set_mode(), but the calibration must happen only after dwc3_host_init() but phy_set_mode() is called either after of before it. With this patch enumeration happens correctly and a super speed device is recognized as such. Rebased onto v4.13. It also applies cleanly to Felipe's testing/next.
