tcpci module in Kernel 5.15.74 with PTN5110 not working correctly

tcpci module in Kernel 5.15.74 with PTN5110 not working correctly

[Christian Bach]

Hello

For a few weeks now I am trying to make the PTN5110 chip work with the new Kernel 5.15.74. The same hardware setup was working with the 4.19.72 Kernel. The steps I took so far are as follows:
1. Study the Documentation and look at example Device Tree's in the Kernel
2. Try out different Device Tree configurations derived from the Documentation and examples
3. I did look on Stackoverflow, the NXP and other forums for any similar issue but could not find any
4. Updating the Kernel to the newest Version I was able to find: 5.15.74 (Hash: f0bee94053065c7cb8eacadfdd6bf739a2042b35 in Repo: git://git.yoctoproject.org/linux-yocto.git;branch=v5.15/standard/base)
5. Downgrade to the earliest Kernel possible: v5.10-rc1 (Hash: 3650b228f83adda7e5ee532e2b90429c03f7b9ec in Repo: git://git.yoctoproject.org/linux-yocto.git;branch=v5.15/standard/base)

None of those steps had any effect. Every time I plug in a USB-A to USB-C cable the Kernel gets stuck in the ISR until I unplug the cable. (Attaching a full USB-PD capable Power Source over a USB-C cable works fine)
This results in an unreasonable high CPU usage (most of the times the CPU gets blocked completely).

I did analyze the I2C bus and found that the old Kernel did change many configurations after the A-C cable got attached while the new Kernel does nothing (please see logs below).
I also did compare what happens on the I2C bus during chip initialization but did not find any mentionable differences.

My HW setup is an i.mx6ul with the PTN5110 attached on I2C4.

Thank you for answering. I did try a Kernel from 1 year ago (11. December 2020 - with the Hash b5206275b46c30a8236feb34a1dc247fa3683d83). But this Kernel had the exact same behavior. 
I even wanted to go back further the when the tcpm module got it's own subdirectory (v4.20 - 20. September 2018 - Hash ae8a2ca8a2215c7e31e6d874f7303801bb15fbbc) to see if it still worked at that time but my build system was not able to build it.

Greg asked for you to test with a v5.4.y kernel. ae8a2ca8a221..b5206275b46c30a82
is again a pretty large step with more than 100 commits in the drivers/usb/typec/tcpm/
directory.

Also, it might be useful to provide the respective kernel logs.

Thanks,
Guenter

Ok

I now tested the whole thing also with some of the v5.4.y kernels. Just to avoid misunderstandings I listed all my tests below:

I would love to send some kernel logs but I can not see any entry in dmesg. Can you instruct me how to get the corresponding kernel logs?

Greg asked for you to test with a v5.4.y kernel. ae8a2ca8a221..b5206275b46c30a82 is again a pretty large step with more than 100 commits in the drivers/usb/typec/tcpm/ directory.

Also, it might be useful to provide the respective kernel logs.

Thanks,

Thanks a lot for the detailed report. It would be great if you can
send actual crash logs. Maybe that problem is fixable in v5.4.y.

Can you also test v5.0 .. v5.3 ? Mainline would be best (not v5.0.x but v5.0) ?

This won't be in dmesg; that would be way too noisy since it logs
each state machine action.

You should find the logs in /sys/debug/kernel/usb/tcpm-<index>.
In older kernels it is just a file, in more recent kernels it is a
directory with files in it. In really old kernels it is
/sys/debug/kernel/tcpm/tcpm-<index>. If you don't immediately find
the file(s), just search for files with "tcpm" in the name in
/sys/kernel/debug.

Hope this helps,

Thanks,
Guenter

I was able to retrieve these Logs for the 5.15.74 and 4.19.72 Kernel. Unfortunately I am not familiar enough with this subsystem to find the problem myself.
Regardless, what stands out to me (as it already did when I posted the I2C communication) is that the module in the old kernel is doing much more things when a cable gets attached. To me it seams as if a vital handling method is not being called in case a non-PD capable cable gets attached. As you can see in the log at the end the PD-capable power supplies work just fine.

AW: tcpci module in Kernel 5.15.74 with PTN5110 not working correctly

[Christian Bach]

Hello everyone

We finally found a solution to the problem we had with the PTN5110 Chip and the Kernel Module tcpci that manages this chip in 5.15.xx Kernel. NXP Patched their Kernel a while ago (https://source.codeaurora.org/external/imx/linux-imx/commit/drivers/usb/typec/tcpm/tcpci.c?h=lf-5.15.y&id=2a263f918b25725e0434afa9ff3b83b1bc18ef74) and we reimplemented the NXP patch for the Kernel 5.15.91. I attached my reworked patch below:

Can you submit this as a real fix so that we can apply it properly?

This should probably clear all fault bits. Also, the specification
suggests to clear the fault bits prior to clearing fault alert event.

TCPC_FAULT_STATUS_MASK is a register address, so this doesn't really
make sense. If the idea is to reset all active fault bits, just write
0xff. However, if faults are not really handled, it might be better
to set TCPC_FAULT_STATUS_MASK to 0 instead of enabling fault alerts.

It would probably be better to actually handle faults, but that may
be more complex, and someone would have tho be able to test any
changes.
