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.

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.

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

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

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

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.

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).

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.
