[1.] One line summary of the problem:
DWC3 USB 3.0 not working on Odroid-XU4 with Exynos 5422

[2.] Full description of the problem/report:
No usb 3.0 devices are being detected when attached while USB 2.0
devices work on the same port.
USB 3.0 works after applying patches [9.1] and [9.2], but seems to be
buggy. The usb hub is redetected every time an usb device is attached.

Looks like the hub GetPortStatus request fails with protocol error.

Reading xhci root hub port status is mostly just register reads and writes. It
shouldn't include any actual transfers that could return -EPROTO

So this is not the root hub? but a external or integrated on your board, right?

The protocol error -71 is returned at transfer errors or if device stalled.

Adding more xhci debugging options could show something:
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control

The additional patches that makes things somehow work involve tuning the PHY,
this is an area I'm not familiar with

I'm sorry, I should have said that this is the dmesg output with the
patches applied. Without them there is no output at all when I attach
an usb 3.0 device.

There are two dwc3 ports in the SoC : one for Gbit Ethernet another
one for on-board GL3521 USB 3.0 hub controller.

I fell that Ethernet driver r8152 is not getting registered to
xhci-hcd to bus port 06
which lead to other ports to miss configure, some time the Ethernet
port get register to bus port 04

Their is also a possibility that all the port are not getting proper
power from the S2MPS11 PMIC
and possible some reset of the phy is needed to reconfigure the exynos
USB HSIC controller.

Today I've tested v4.8-rc7 (without the patches above). The USB 3.0
ports have stopped working completely for me. Neither USB 2.0 nor USB
3.0 are being detected. The Ethernet port does not work, too. The USB-
2.0-only Port works.

There also a new problem: my XU4 does not reboot or poweroff anymore.
When I force-remove the dwc3 module reboot / poweroff works again.


There are some failures in the dmesg log, see below.

Best regards,
Michael

These patches are required to get USB super-speed working on Exynos5420/5800.
But they did not make to upstream. There was resistance on adding new
phy_calibrate()
callback.

Without these patches the Exynos5420/5800 will enumerate all
super-speed capable devices
as high-speed devices.
Last time we checked with exynos542x smdk boards and peach-* boards,
we could get the
Super - speed devices working. I have not tested odroid anytime so
don't have much idea about the
its intricacies.
I guess Anand was able to use these patches to get his kernel working in past.

When you have a downstream on-board usb hub, ideally it should be able
to detect the devices
and not reset everytime you connect a new device (like you mentioned earlier).
There can be two possible reasons why the hub keeps getting reset ever
after applying the above
mentioned patches:
1) the clock rates are not proper.
2) the regulator load setting is not enough to drive the hub.

Anand, can you please point Michael to an older kernel with which you
could test usb on odroid successfully ?
You can compare the clocks with an older version and see if there'a
any difference.

Any possibility of any other framework (such as, bus-freq) trimming
down the clock - rates ?

The patches don't work anymore with 4.8-rc* / 4.8. They worked - but very
unstable - with 4.7.

One more problem appeared since one of the 4.8-RCs: reboot hangs when the dwc3
module is loaded. If I unload it before reboot / shutdown everything is fine.

This clock should have been 200MHz.

The clocks are same across working/non-working.
Is it possible to bisect the commit that's causing hang for 4.8x ?

Adding few of the folks from Samsung who can test dwc3 usb on smdk/peach boards.
+Alim, Pankaj

Hi Alim, Pankaj,
can you please give a try with 4.8 kernel on peach/smdk542x board and
see if dwc3 usb works or not.
You may need to the patches mentioned in [9.1] and [9.2] mentioned above.

Dose not help. it's not useful at all.

What I feel is that their need to be some reset of usb phy so that
device are assigned to respective bus ports.

Bus 06.Port should register the Realtek Ethernet r8153 device.
But I am not able to trace out how it's should happen.

The phy resets are what we do in the phy-exynos5-usbdrd driver. In
addition to what we
have currently in this phy driver, we just need the phy calibration
patch [1] for phy configurations.

This shows the ethernet device gets detected on the high-speed port of one
of the controller.
The lsusb output for kernel v4.7.x posted by Michael show that the
ethernet device got detected on super-speed port of the controller.
So, there seems to be a difference between the two.
Or, is this how it is behaving ?

Is this lsusb output on 4.8 kernel with the patch [1] ?

If i understand, below is how the configuration looks like on the board?

With other patches it miss behaves and the ethernet land onto another bus
port
.

Yes correct.

Yes this is correct mapping of usb ports and ethernet on the board.

Below is the schematic of the board.

http://dn.odroid.com/5422/ODROID-XU4/Schematics/XU4_MAIN_REV0.1_20151202.pdf

I have couple of questions so if you can help me out.

1 > Their is no vbus pin connector to the usb ports ?

2 > I have also tried to configure usbdrd_dwc3_0/1 nodes with no luck
                        snps,usb3_lpm_capable;

                        snps,dis_u2_susphy_quirk;

3 > do you feel their could be way to reset the USB PHY (ethenet)
       either though the DTS using gpio and pincrt

4 > how should be the port mapping done to the usb hub.
      Odroid XU4 has 2 usb 3.0 and 1 ehci port.
      Odroid XU3 has 1 usb 3.0 and 1 usb 3.0 otg port and 4 ehci
port


I would like to know how to debug low level debug of USB connection.
so that we could solve the issue.

Thanks for you help in looking to this, please guide me.
Attach is the logs of lsusb -v and console output.

[c499ff71ff2a281366c6ec7a904c547d806cbcd1] usb: dwc3: core: re-factor init and exit paths
This patch causes both the hang on reboot and the lsusb hang.

How to reproduce? Why don't we see this on x86 and TI boards? I'm
guessing this is failed bisection, as I can't see anything in that
commit that would cause reboot hang. Also, that code path is *NOT*
executed when you run lsusb.

I've tested this procedure multiple times to be sure:

- checkout c499ff71, compile, boot the odroid
- run lsusb -v => lsusb hangs, can't terminate with ctrl-c
- hard reset, after boot run poweroff or reboot => board does not completely power off / reboot (see log below)
- revert c499ff71, mrproper, compile, boot the odroid
- run lsusb -v => shows full output, not hanging
- run reboot or poweroff => board powers off / reboots just fine


dmesg poweroff not working:

=> at this point removing the sd card would show a message 
"removed mmc0" (not sure what the real message was...) so the board is not completely off.

I did some more tests with next-20161016. Reverting / commenting out
one part of your patch "solves" the lsusb hang, the reboot problem
and also the "debounce failed" message. [1]
Another "solution" is to call phy_power_off before phy_power_on. [2]

Disclaimer: I have no idea what I was doing ;-) These were just some
simple trial-and-error attempts that maybe help to find the real
cause of the problems.
