I'm not sure why this it only works with the driver compiled into the
kernel nor why it needs a hard reset or why it was the line was dropped
when the patch was accepted. Would be great to get some feedback of the
authors.
When XHCI driver is compiled into the kernel are the relevant PHY drivers
compiled in as well?
Only CONFIG_USB_PHY=y (I took the config from the linux-image-4.19.0-1-armmp_4.19.13-1_armhf.deb Debian package as a basis where this is the default).

I confirm that on Odroid XU4 USB 3.0 works only when all related drivers
(dwc3, xhci and exynos5 drd phy) are compiled into the kernel. If they
are compiled as modules, USB 3.0 calibration doesn't work. The mentioned
patch doesn't fix anything.

I've just tried Linux v5.0-rc5 with the Debian config and USB_XHCI_PLATFORM=y and it works, thanks!

Is there a way to make it work with xhci compiled as a module, so it would work in Debian out of the box?

Cheers Jochen
