I feel this is long standing issue with phy-exynos5-usbdrd.c
with following patch missing.

[0] https://patchwork.kernel.org/patch/5204471/

with some more updated to phy-exynos5-usbdrd.c
I was able to bring the phy up in cold boot.
but when I perform warm boot the issue persist.

Just build and tested the 4.13.0-rc1-next-20170721.
so kernel is good enough to enumerate the usbdrd_dwc3_1 (usb port 6,5)
but this failed to enumerate the usbdrd_dwc3_10 (usb port 4,3).

you got rid of*all*  context. I have no idea what you're replying

I tested with that commit on top of v4.13-rc1 and USB seems to
be working properly on Odroid XU4, the mouse is working.

Thanks for your tips and input.

I was going to 'git bisect' over this weekend.
But I will now check the 4.13.0-rc1-next-20170721
and let you all know if this resolves the issue.

no we do not. And that patch of yours would actually regress many
things. For one, you're moving dwc3_setup_phy() before we even *get* a
reference to the PHY. Not to mention that dwc3_core_is_valid() only
checks the revision register to verify that we're dealing with a *real*
Synopsys IP.

Your patch is not only unnecessary, it's also wrong.

No, as I wrote In my patch, it's on top of

you got rid of *all* context. I have no idea what you're replying

Hi,

I've send a patch for this some time ago here:

This goes along with the patch in this thread:

@Felipe can I do anything more to get it accepted upstream?

Hi Anand,

Beside Felipe's comment, I do not have XU4. I cannot reproduce it on
XU3-Lite (but there is difference in USB2 and USB3, AFAIR).

$ uname -a
Linux odroidxu3 4.13.0-rc1-00071-ge06fdaf40a5c #1051 SMP PREEMPT Wed Jul 19 
22:07:41 CEST 2017 armv7l GNU/Linux
$ lsusb

Try to follow Felipe's advice of using vanilla kernel from Linus and
bisecting it.

Best regards,
Krzysztof

Dude, you have 27 thousand patches on top of v4.13-rc1??? Try vanilla
v4.13-rc1 and try a git bisect.

USB 3.0 is broken on Odroid Xu4 on latest kernel

[Anand Moon]

Hi Krzysztof,

Today I tried to compile the latest kernel for Odroid xu4.
using exynos_defconfig I build and loaded the kernel.
but to my surprise usb 3.0 device and missing.

Full dmesg can be found on blow link.
https://pastebin.com/K3xfPCPe

The reason for failed is below.

[7.187096] usb usb4-port1: connect-debounce failed

I tried to debug this but failed to find the root cause.
Nothing is connected to the UBS 3.0 port for the failure to cause.

If I load old kernel it seen to work correctly.
If you provoid some input I will give this a try.

Best Regards
-Anand
