When xhci_requires_manual_halt_cleanup() was written it wasn't clear
that the xhci internal endpoint halt state always needs to be cleared
with a reset endpoint command. Functional stall cases additionally halt
the device side endpoint which requires class driver to clear the device
side halt with a CLEAR_FEATURE(ENDPOINT_HALT) request as well.
Clean up, rename, and make sure the new function always return true
when internal endpoint state is halted, including stall cases.
Based on related cleanup suggestion code by Niklas Neronin

Remove debug messages that served as sanity checks during the initial
implementation phase of underrun/overrun completion codes. These checks
are now unnecessary.
Instead, improve the default debug messages for underrun/overrun events,
so that they are consistent with the reset of the completion codes.

Improve error message for unknown transfer event without a TRB, by also

Move handling transfer events without a target transfer TRB into
handle_transferless_tx_event(), this type of event does not utilize the
rest of handle_tx_event() and as a result it's better to separate it
into a dedicated function.
Additionally, this change reduces handle_tx_event()'s size and makes it
more readable.
[Mathias: Simplify code to return helper function value directly. This
removes the second xhci_err() message for untargeted and unexpected
event completion types]

This is a preparation patch for switching from custom segment list
handling to using list.h functions.
Contain all segment re-numbering in xhci_link_rings() which links two
segments lists together, and performs all necessary adjustments for
them to fit together.
No need to send segment number to xhci_alloc_segments_for_ring()
as a parameter after this.

Older 0.95 xHCI hosts and some other specific newer hosts require the
chain bit to be set for Link TRBs even if the link TRB is not in the
middle of a transfer descriptor (TD).
move the checks for all those cases into one xhci_link_chain_quirk()
function to clean up and avoid code duplication.
No functional changes.

Remove 'num_trbs' from 'xhci_td' as it's no longer used following the
removal of 'num_trbs_free' tracking in commit 2710f8186f88 ("xhci: Stop
unnecessary tracking of free trbs in a ring").
Tracking of 'num_trbs_free' is still performed in xhci DbC, but it does not

xhci DbC driver polls the host controller for DbC events at a reduced
rate when DbC is enabled but there are no active data transfers.
Allow users to modify this reduced poll interval via dbc_poll_interval_ms
sysfs entry. Unit is milliseconds and accepted range is 0 to 5000.
Max interval of 5000 ms is selected as it matches the common 5 second
timeout used in usb stack.
Default value is 64 milliseconds.
A long interval is useful when users know there won't be any activity
on systems connected via DbC for long periods, and want to avoid
battery drainage due to unnecessary CPU usage.
Example being Android Debugger (ADB) usage over DbC on ChromeOS systems
running Android Runtime.

The transferred length is incorrectly zeroed for cancelled isoc
transfer TDs when the transfer ring stops on a cancelled TD with
a 'Stop - Length Invalid' completion code.
Length was always set to zero in these cases even if it should be
set to the sum of the TRB transfer block lengths up to
the TRB the ring stopped on, _excluding_ the one stopped on.
No issues reported due to this isoc case. Found while inspecting
related case in bulk transfer 'Stop - Length Invalid' handling.
Change this so that 'Stop - Length Invalid' transfer completion
cases always sum up TRB lengths instead of report a zero length.

Replace SET_RUNTIME_PM_OPS() with its modern RUNTIME_PM_OPS()
alternative.
The combined usage of pm_ptr() and RUNTIME_PM_OPS allows the compiler
to evaluate if the runtime suspend/resume() functions are used at build
time or are simply dead code.
This allows removing the __maybe_unused notation from the runtime

Add a match function for the onboard_usb_dev driver. Primary
matching is still done through the VID:PID pair, as usual for
USB devices. The new match function checks in addition whether
the device has a device tree node, which is a needed for using
the onboard_usb_dev driver.
Remove the check for a device tree node from _probe(), the new
match functions prevents devices without DT node from probing.

FM350-GL is 5G Sub-6 WWAN module which uses M.2 form factor interface.
It is based on Mediatek's MTK T700 CPU. The module supports PCIe Gen3
x1 and USB 2.0 and 3.0 interfaces.
The manufacturer states that USB is "for debug" but it has been
confirmed to be fully functional, except for modem-control requests on
some of the interfaces.
USB device composition is controlled by AT+GTUSBMODE=<mode> command.
Two values are currently supported for the <mode>:
40: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB
41: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB+AP(LOG)+AP(META) (default value)
[ Note that the functions above are not ordered by interface number. ]
Mode 40 corresponds to:

In the aspeed UDC setup, we configure the UDC hardware with the assigned
USB device address.
However, we have an off-by-one in the bitmask, so we're only setting the
lower 6 bits of the address (USB addresses being 7 bits, and the
hardware bitmask being bits 0:6).
This means that device enumeration fails if the assigned address is
greater than 64:
[ 344.607255] usb 1-1: new high-speed USB device number 63 using ehci-platform
[ 344.808459] usb 1-1: New USB device found, idVendor=cc00, idProduct=cc00, bcdDevice= 6.10

[ 352.909431] usb 1-1: device descriptor read/all, error -71
Use the correct mask of 0x7f (rather than 0x3f), and generate this
through the GENMASK macro, so we have numbers that correspond exactly
to the hardware register definition.

avoid deadlock
When config CONFIG_USB_DWC3_DUAL_ROLE is selected, and trigger system
to enter suspend status with below command:
echo mem > /sys/power/state
There will be a deadlock issue occurring. Detailed invoking path as
below:
dwc3_suspend_common()
spin_lock_irqsave(&dwc->lock, flags); <-- 1st
dwc3_gadget_suspend(dwc);
dwc3_gadget_soft_disconnect(dwc);
spin_lock_irqsave(&dwc->lock, flags); <-- 2nd
This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix
NULL pointer dereference in dwc3_gadget_suspend") that removes the code
of checking whether dwc->gadget_driver is NULL or not. It causes the
following code is executed and deadlock occurs when trying to get the
spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3:
Remove DWC3 locking during gadget suspend/resume") that forgot to remove
the lock of otg mode. So, remove the redundant lock of otg mode during
gadget suspend/resume.

The device_for_each_child_node() macro requires explicit calls to
fwnode_handle_put() in all early exits of the loop if the child node is
not required outside. Otherwise, the child node's refcount is not
decremented and the resource is not released.
The current implementation of pmic_glink_ucsi_probe() makes use of the
device_for_each_child_node(), but does not release the child node on
early returns. Add the missing calls to fwnode_handle_put().

Some LG Gram laptops report a bogus connector change event after a
GET_PDOS command for the partner's source PDOs, which disappears from
the CCI after acknowledging the command. However, the subsequent
GET_CONNECTOR_STATUS in ucsi_handle_connector_change() still reports
this bogus change in bits 5 and 6, leading to the UCSI core re-checking
the partner's source PDOs and thus to an infinite loop.
Fix this by adding a quirk that signals when a potentially buggy GET_PDOS
command is used, checks the status change report and clears it if it is a
bogus event before sending it to the UCSI core.

Sometimes errors are seen, when doing DR swap, like:
[ 24.672481] ucsi-stm32g0-i2c 0-0035: UCSI_GET_PDOS failed (-5)
[ 24.720188] ucsi-stm32g0-i2c 0-0035: ucsi_handle_connector_change:
GET_CONNECTOR_STATUS failed (-5)
There may be some race, which lead to read CCI, before the command complete
flag is set, hence returning -EIO. Similar fix has been done also in
ucsi_acpi [1].
In case of a spurious or otherwise delayed notification it is
possible that CCI still reports the previous completion. The
UCSI spec is aware of this and provides two completion bits in
CCI, one for normal commands and one for acks. As acks and commands
alternate the notification handler can determine if the completion
bit is from the current command.
To fix this add the ACK_PENDING bit for ucsi_stm32g0 and only complete
commands if the completion bit matches.

Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong

triggers a warning in usb_submit_urb().
Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.
Unfortunately, this patch has not been tested on real hardware.
