Hi all,
This is the second version of patches in this thread.
The series fixes problems with enumerating of SuperSpeed devices
on an Odroid XU3. There was a patch series from Vivek Gautam in
circulation, but it got lost somehow. Please see:

I adapted his patch so that it does not use a hacky solution to force
additional initialization in order for calibration to happen.
With this patch enumeration happens correctly and a super speed device
is recognized as such.
@Kishon:
As far as I understand what you suggest is to move phy_init() and
phy_power_on() invocations from dwc3/core.c to xhci-plat, but,
to the best of my knowledge, they are needed in device mode, too.
Changes since v1:
- added calibrate() callback to phy
- used calibrate() instead of reset() to trigger the calibration
