USB / Thunderbolt changes for 7.4-rc1
Here is the big set of USB and Thunderbolt changes for 7.4-rc1.
Included in here are:
- thunderbolt driver updates and fixes
- lots of dt schema conversions
- usb gadget driver fixes (and a new maintainer!)
- usb core fixups with some interactions with the driver core
- usb serial updates and fixes for scan-found "issues"
- xhci driver updates
- typec driver updates
- dwc3 driver updates
- lots of usb gadget driver fixes for syzbot found "problems"
- lots of other small USB driver fixes for randomly reported problems.
All of these have been in linux-next with no reported issues.

This commit (254261381538: "usb: typec: ucsi: retry init when the PPM
answers early commands incorrectly")
> Jacob Riff (1):
> usb: typec: ucsi: retry init when the PPM answers early commands incorrectly
results in a hundred and one lines of
ucsi_acpi USBC000:00: error -ENODEV: con1: failed to get usb role switch
for me on every boot on my laptop.
Before that commit, I got a single
ucsi_acpi USBC000:00: error -ENODEV: con1: failed to get usb role switch
ucsi_acpi USBC000:00: error -ENODEV: PPM init failed
but now it apparently retries that thing a hundred times before
finally giving up wth
ucsi_acpi USBC000:00: PPM init failed, stop trying
and honestly, this all seems rather excessive. Retry ten times a
second, for ten seconds? As far as I know, this has never succeeded in
the history of this laptop, and it has no bad effects apart from the
silly messages.

Hi Linus,
Sorry about the noise. As written the retry catches every -ENODEV,
including ucsi_register_port() failing on the role switch lookup, which
no retry can change. Fix follows in this thread: it retries only the
PPM-not-ready case, for one second instead of ten, and has been through
six boots on the machine the retry was written for (three hit the race,
all recovered).
As far as I can see, the -ENODEV in your log can only come from the
!CONFIG_USB_ROLE_SWITCH stub of fwnode_usb_role_switch_get(); the real
one returns a switch, NULL or -EPROBE_DEFER. If that is your config,
UCSI has never been able to init there: TYPEC_UCSI builds without
USB_ROLE_SWITCH but then fails on it at probe. That is a separate,
older problem.
Jacob

Commit 254261381538 ("usb: typec: ucsi: retry init when the PPM
answers early commands incorrectly") makes ucsi_init_work() retry
ucsi_init() on -ENODEV and -EINVAL, a hundred times over ten seconds,
to cover a PPM that is not ready to answer commands correctly for a
short window during boot.
It catches more than that. ucsi_register_port() also fails with
-ENODEV when no USB role switch is available, and logs that at error
level, so every retry runs it again and logs it again. Where a machine
without a usable role switch used to log
ucsi_acpi USBC000:00: error -ENODEV: con1: failed to get usb role switch
ucsi_acpi USBC000:00: error -ENODEV: PPM init failed
it now logs a hundred and one copies of the first line, followed by
"PPM init failed, stop trying", on every boot, and the retries can
never succeed there.
Have ucsi_init() report the two not-ready cases as -EAGAIN instead:
GET_CAPABILITY reporting zero connectors, and the PPM rejecting a
standard command (-EINVAL from ucsi_read_error(), the only -EINVAL
expected once the PPM reset has succeeded). Retry only -EAGAIN and, as
before that commit, -EPROBE_DEFER. Every other error is reported once
and init stops, as it did before.
Also give -EAGAIN its own budget. The hundred retries over ten seconds
belong to the USB role switch wait. On the machine the retry was
written for, every observed failure recovered on the first or second
retry, so ten retries over one second is plenty. A PPM that
permanently rejects a command now logs "possible UCSI driver bug" up
to eleven times in that second, on hardware where init already failed
before.

Tested on the machine from the Fixes commit (Lenovo ThinkPad X1 Carbon
Gen 14, this patch applied to the 7.2.6 driver): 6 boots, 3 hit the
race, all 3 recovered through the -EAGAIN path (two on the first retry,
one on the second), none ended with UCSI unusable. The single-report
path for a permanent -ENODEV from ucsi_register_port() is verified by
inspection only; no machine here has that configuration.
