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.

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.

Introduce a new 'of-fullname-regex' property that takes a regular

matching controllers that don't have a unique DT address across sibling

One particular example of where this is needed is on MT8195 which has
multiple USB controllers described by two level deep nodes and using the
ranges property:
ssusb2: usb@112a1000 {
reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>;

The current error logs do not show the firmware name and size for the
tps6598x. On the other hand, this information is provided for the
tps25750. Both implementations have access to that information, and the
existing message for the tps25750 can be used for the tps6598x without
extra modifications.

tps_request_firmware() reads the firmware name and there is no need to
repeat the action in the device-specific implementations of the firmware
update mechanism.
Provide the firmware name as a parameter in tps_request_firmware() to
avoid repetitive operations in the device-specific implementations.

There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:
timeout = wait_for_completion_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Retimers support lane margining as well so make this available through
debugfs in the same way as we do for the USB4 ports. When this is
enabled we also expose retimers on the other side of the cable because
typically margining is implemented only on direction towards the cable.
However, for the retimers on the other side of the cable we do not allow
NVM upgrade to avoid confusing the existing userspace (the same retimer
may now appear twice with different name) and is probably not a good
idea anyway.

In order to add lane margining support for retimers make the margining
functions take sideband target and retimer index as parameters. This
makes it possible to access both router and retimer sideband using the
same functions.
