Dear Linux folks,
Linux 4.17-rc5 shows the error below on the Dell XPS 13 9370 with Debian
Sid/unstable.
```
[…]
[ 0.440240] usb: port power management may be unreliable
[ 0.441358] usbcore: registered new interface driver usb-storage
[ 0.441367] usbcore: registered new interface driver usbserial_generic

[ 0.441518] ucsi_acpi: probe of USBC000:00 failed with error -12
[…]
```
1. Are the ioremap and ucsi_acpi error related or is a separate report
needed?
2. Do you know the reason for the ucsi_acpi error?
Kind regards,
Paul

The ioremap error is what causes ucsi_acpi to fail the probe call (-12
is "out of memory".)
> 2. Do you know the reason for the ucsi_acpi error?
the call to ioremap failed.
Does this device really have a working typec connector? Does normal USB
devices work with it?

Dear Greg,
As always, thank you for the prompt response.

Just to avoid misunderstandings, no device was connected to the laptop
during my test.
But, from other boots, the Dell docking station TB16 kind of works with
it, so I’d say the USB Type-C connector is working.

Sorry for being ignorant, but could you please tell me what normal USB
devices are?
Kind regards,

Ok, good, this might just be the acpi tables not set up properly for
this type of connection. Odd that the tables show it should work,
Heikki should know more about this.

If you plug a USB typeC device into this port, does it work? A docking
station is a little bit "different" in that it usually uses the PCIe
connection, not the USB connectors. Or at least that's how my Dell
docking station works last time I tried it[1]
thanks,
greg k-h
[1] When the power supply for the docking station is bigger than the
laptop's power supply, you begin to wonder what is in that thing and
stop using it after a while...

The firmware probable has not implemented UCSI on this board. I think
Dell always supplies the ACPI device node for UCSI in their acpi
tables. The _STA method in that device node is then used to inform the
OS if the interface exists or not. The return value for _STA comes
probable from BIOS, so this is most likely a BIOS problem.
Please note that UCSI will only supply status information to the
operating system, so the USB Type-C ports will function normally even
without it. The ports are handled in firmware on these platforms.
Paul, do you have the latest BIOS?

I had the latest firmware

until today, when 1.3.2 with the changes below was released [1].
Mario, it’d be great, if the Dell firmware team could start testing with
Linux releases too to find such issues. Mario, could you please also
check internally if the Dell firmware team is aware of the issues and
can incorporate a fix. (I really wish the firmware would be free
software, so that these issues could be fixed ourselves.)

It’ll take me up to some days to get my hands on the device again. But
the update should be easy enough thanks to Dell supporting fwupd with
UEFI Capsule and uploading their updates to the Linux Vendor Firmware
Service [2].

Paul,
The team that sustains platforms does perform Linux testing, but it's not
centered around latest upstream kernel and it's also functionally based (not
reviewing dmesg for new kernel errors) so there are changes in
expectations (viewed as regressions) as you find from time to time.

Heikki,
I confirmed with internal team that UCSI is implemented on XPS 9370
and was confirmed to be working properly with Windows 10 RS2+.
The reason that _STA is responding on this device node now but wasn't
previously is it wasn't exposed in Linux until 4.16 when the Win 10 RS2
OSI string started to respond.
Intel should internally have some XPS 9370 you can remotely access if
you would like to poke around ACPI tables some.

I think the best description here is "Non-Thunderbolt" USB type C device.
Some examples:
There are Dell docking stations with Thunderbolt (TB16) or without (WD15).
You can also pick up little dongles for ethernet or combo dongles for
ethernet/VGA/HDMI/etc.
Anything non-Thunderbolt would satisfy what Greg was looking for.

Mostly to satisfy letting the docking station work with beefier machines and
still deliver power up to what USB PD will negotiate.
I think they can actually run with smaller power supplies but you will need
something "a little" bigger than regular system power supply to power the
dock and system both.

Given the date of my docking station (2+ years old), I would be _amazed_
if it could do USB PD. But I should go try it, my existing Dell laptop
doesn't support that, but I have an Acer here, along with some
chromebooks that do.
I guess I need to go get the latest Dell laptop, "just to test" with :)

Just to double check: "UCSI was confirmed working properly", so not
"the Type-C ports were confirmed working properly"?

OK.

I will try get access to XPS 9370, but with the acpi tables, if
somebody could just send me acpidump, that would be enough:

Anything non-Thunderbolt and non-display.
With the display adapters you would be in DisplayPort alternate mode,
and you would again not be testing a normal USB device.
It never hurts to check that, but I think it's safe to assume that the
ports are functioning normally if the Thunderbolt dock was working.
Unless I'm mistaken, even the xHCI USB host controller behind the
USB Type-C (thunderbolt) ports is actually part of the thunderbolt
controller.

UCSI was confirmed working properly. FWIW it's a certification requirement
in Windows.

In this laptop yes that's true, but isn't a general statement. It's possible
to have USB split mode (ie XHCI comes from PCH).

OK, thank you for confirming that.

I now have the XPS 9370 ACPI tables.

Hey guys!
Just to let you know that I have the same problem on Dell Inspiron 13
7370. Yesterday, I made a test on 4.17RC7 together with the newest BIOS
1.8.0 (released the 1st June 2018) and the problem is still there.
dmesg | grep "error" gives
[ 5.888091] ioremap error for 0x9f935000-0x9f936000, requested 0x2,
got 0x0
[ 5.888158] ucsi_acpi: probe of USBC000:00 failed with error -12
Do not hesitate if you need more information.
Have a nice day,
Kacper
