Make sure to also limit the amount of soft reset retries for transaction
errors on streams in cases where the transaction error event doesn't point
to any specific TRB.
In these cases we don't know the TRB or stream ring, but we do know which
endpoint had the error.
To keep error counting simple and functional, move the current err_count
from ring structure to endpoint structure.

Disable U3 suspended ports in hibernate S4 poweroff_late for systems
with XHCI_RESET_TO_DEFAULT quirk, if wakeup is not enabled.
This reduces the number of self-powered usb devices from surviving in
U3 suspended state into next reboot.
Bootloader/firmware on these systems can't handle usb ports in U3, and
will timeout, causing extra delay during reboot/restore from S4.
Add pci_poweroff_late() callback to struct usb_hcd to get this done at
the correct stage in hibernate.

some Intel Alder Lake xHC hosts on ChromeOS platforms need special
workarounds touching port registers at xHC pci host hibernate.
Export xhci_port_state_to_neutral() and xhci_find_slot_id_by_port()
so they can be called from xhci-pci.c and thus the xhci-pci module.

ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.
This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset
host back to default state at shutdown").
The issue it fixes is a ~20s boot time delay when booting from S5. It
affects ADL-N devices, and ADL-N support was added starting from v5.16.

When HCE(Host Controller Error) is set, it means that the xhci hardware
controller has an error at this time, but the current xhci driver
software does not log this event.
By adding an HCE event detection in the xhci interrupt processing
interface, a warning log is output to the system, which is convenient
for system device status tracking.

A request to set the line speed to B0 is used to hang up a modem
connection by deasserting the modem control lines.
Note that there is no need reconfigure the line speed in hardware when
B0 is requested (even if some drivers do set it to an arbitrary value
for implementation or protocol reasons).

dwc->desired_dr_role is changed by dwc3_set_mode inside a spinlock but
then read by __dwc3_set_mode outside of that lock. This can lead to a
race condition when very quick successive role switch events happen:
CPU A
dwc3_set_mode(DWC3_GCTL_PRTCAP_HOST) // first role switch event
spin_lock_irqsave(&dwc->lock, flags);
dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_HOST
spin_unlock_irqrestore(&dwc->lock, flags);
queue_work(system_freezable_wq, &dwc->drd_work);
CPU B
__dwc3_set_mode
// ....
spin_lock_irqsave(&dwc->lock, flags);
// desired_dr_role is DWC3_GCTL_PRTCAP_HOST
dwc3_set_prtcap(dwc, dwc->desired_dr_role);
spin_unlock_irqrestore(&dwc->lock, flags);
CPU A
dwc3_set_mode(DWC3_GCTL_PRTCAP_DEVICE) // second event
spin_lock_irqsave(&dwc->lock, flags);
dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_DEVICE
spin_unlock_irqrestore(&dwc->lock, flags);
CPU B (continues running __dwc3_set_mode)
switch (dwc->desired_dr_role) { // DWC3_GCTL_PRTCAP_DEVICE
// ....
case DWC3_GCTL_PRTCAP_DEVICE:
// ....
ret = dwc3_gadget_init(dwc);
We then have DWC3_GCTL.DWC3_GCTL_PRTCAPDIR = DWC3_GCTL_PRTCAP_HOST and
dwc->current_dr_role = DWC3_GCTL_PRTCAP_HOST but initialized the
controller in device mode. It's also possible to get into a state
where both host and device are intialized at the same time.
Fix this race by creating a local copy of desired_dr_role inside
__dwc3_set_mode while holding dwc->lock.

Unify error handling at the end of the function, reducing the risk of
missing something on one of the error paths.
Moving the increment of opts->refcnt later means there is no need to
decrement it on the error path and is safe as this is guarded by

The embedded struct cdev does not have its lifetime correctly tied to
the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN
is held open while the gadget is deleted.
This can readily be replicated with libusbgx's example programs (for
conciseness - operating directly via configfs is equivalent):
gadget-hid
exec 3<> /dev/hidg0
gadget-vid-pid-remove
exec 3<&-
Pull the existing device up in to struct f_hidg and make use of the
cdev_device_{add,del}() helpers. This changes the lifetime of the
device object to match struct f_hidg, but note that it is still added
and deleted at the same time.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

Some port drivers may want to set a Type-C partner as a parent for a
USB Power Delivery object, but the Type-C partner struct isn't exposed
outside of the Type-C class driver. Add a wrapper to
usb_power_delivery_register() which sets the provided Type-C partner
as a parent to the USB PD object. This helps to avoid exposing the
Type-C partner's device struct unnecessarily.

USB drivers do not need to call usb_set_intfdata(intf, NULL) in their
usb_driver::disconnect callback because the core already does it in [1].
However, this fact is widely unknown, c.f.:
$ git grep "usb_set_intfdata(.*NULL)" | wc -l
215
Especially, setting the interface to NULL before all action completed
can result in a NULL pointer dereference. Not calling
usb_set_intfdata() at all in disconnect() is the safest method.
Add documentation to usb_set_intfdata() to clarify this point.
Also remove the call in usb-skeletion's disconnect() not to confuse
the new comers.

It can take more than one second to check each connector
when the system is resumed. So if you have, say, eight
connectors, it may take eight seconds for ucsi_resume() to
finish. That's a bit too much.
This will modify ucsi_resume() so that it schedules a work
where the interface is actually resumed instead of checking
the connectors directly. The connections will also be
checked in separate tasks which are queued for each connector
separately.

In the process of switching USB config from rndis to other config,
if the hardware does not support the ->pullup callback, or the
hardware encounters a low probability fault, both of them may cause
the ->pullup callback to fail, which will then cause a system panic
(use after free).
The gadget drivers sometimes need to be unloaded regardless of the
hardware's behavior.
Analysis as follows:
=======================================================================
(1) write /config/usb_gadget/g1/UDC "none"
gether_disconnect+0x2c/0x1f8
rndis_disable+0x4c/0x74
composite_disconnect+0x74/0xb0
configfs_composite_disconnect+0x60/0x7c
usb_gadget_disconnect+0x70/0x124
usb_gadget_unregister_driver+0xc8/0x1d8
gadget_dev_desc_UDC_store+0xec/0x1e4
(2) rm /config/usb_gadget/g1/configs/b.1/f1
rndis_deregister+0x28/0x54
rndis_free+0x44/0x7c
usb_put_function+0x14/0x1c
config_usb_cfg_unlink+0xc4/0xe0
configfs_unlink+0x124/0x1c8
vfs_unlink+0x114/0x1dc
(3) rmdir /config/usb_gadget/g1/functions/rndis.gs4
panic+0x1fc/0x3d0
do_page_fault+0xa8/0x46c
do_mem_abort+0x3c/0xac
el1_sync_handler+0x40/0x78
0xffffff801138f880
rndis_close+0x28/0x34
eth_stop+0x74/0x110
dev_close_many+0x48/0x194
rollback_registered_many+0x118/0x814
unregister_netdev+0x20/0x30
gether_cleanup+0x1c/0x38
rndis_attr_release+0xc/0x14
kref_put+0x74/0xb8
configfs_rmdir+0x314/0x374
If gadget->ops->pullup() return an error, function rndis_close() will be
called, then it will causes a use-after-free problem.

A request to Manish Narani (see Link) asked for clarification of the
reference to the config ARCH_VERSAL in the support of Xilinx SoCs with
DesignWare Core USB3 IP.
As there is no response, clean up the reference to the non-existing config
symbol. While at it, follow up on Felipe Balbi's request to add the
alternative COMPILE_TEST dependency.

Probe for omap2430 glue layer is now broken for interrupt resources in
all cases.
Commit 239071064732 ("partially Revert "usb: musb: Set the DT node on the
child device"") broke probing for SoCs using ti-sysc interconnect target
module as the dt node is not found.
Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from
DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as
the IRQ resources are no longer automatically populated from devicetree.
Let's fix the issues by calling device_set_of_node_from_dev() only if the
SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's
populate the resources manually as needed.
Note that once we have updated the SoCs to probe with proper devicetree
data in all cases, this is no longer needed. But doing that requires
patching both devicetree and SoC code, so let's fix the probe issues first.
