Software that has run before the USB4 CM in Linux runs may have disabled
hotplug events for a given lane adapter.
Other CMs such as that one distributed with Windows 11 will enable hotplug
events. Do the same thing in the Linux CM which fixes hotplug events on
"AMD Pink Sardine".

If any software has interacted with the USB4 registers before the Linux
USB4 CM runs, it may have modified the plug events delay. It has been
observed that if this value too large, it's possible that hotplugged
devices will negotiate a fallback mode instead in Linux.
To prevent this, explicitly align the plug events delay with the USB4
spec value of 10ms.

As there will be more USB4 devices that support NVM firmware upgrade from
various vendors, it makes sense to split out the Intel specific NVM
image handling from the generic code. This moves the Intel specific NVM
handling into a new structure that will be matched by the device type
and the vendor ID. Do this for both routers and retimers.
This makes it easier to extend the NVM support to cover new vendors and
NVM image formats in the future.

be active in order to perform NVM firmware upgrade and for this reason
it was disabled when software connection manager is active. However,
this is not necessary for USB4 host routers as this functionality is

USB4 spec defines standard set of registers to be used for receiver lane
margining. This is useful for I/O interface quality and electrical
robustness validation during manufacturing. Expose receiver lane
margining through new debugfs directory "margining" that is added under
each connected USB4 port. Users can then run the margining by writing to
the exposed attributes under that directory.

As we are now enabling full end-to-end flow control to the Thunderbolt
networking driver, in order for it to work properly on second generation
Thunderbolt hardware (Falcon Ridge), we need to add back the workaround
that was removed with commit 53f13319d131 ("thunderbolt: Get rid of E2E
workaround"). However, this time we only apply it for Falcon Ridge
controllers as a form of an additional quirk. For non-Falcon Ridge this
does nothing.

The parent field in struct acpi_device is, in fact, redundant,
because the dev.parent field in it effectively points to the same
object and it is used by the driver core.
Accordingly, the parent field can be dropped from struct acpi_device
and for this purpose define acpi_dev_parent() to retrieve a parent
struct acpi_device pointer from the dev.parent field in struct
acpi_device. Next, update all of the users of the parent field
in struct acpi_device to use acpi_dev_parent() instead of it and
drop it.
While at it, drop the ACPI_IS_ROOT_DEVICE() macro that is only used
in one place in a confusing way.

Use acpi_find_child_by_adr() to find the child matching a given bus
address instead of tb_acpi_find_port() that walks the list of children
of an ACPI device directly for this purpose and drop the latter.
Apart from simplifying the code, this will help to eliminate the
children list head from struct acpi_device as it is redundant and it
is used in questionable ways in some places (in particular, locking is
needed for walking the list pointed to it safely, but it is often
missing).

Low power states (called collectively CLx) are used to reduce

to the host router). This is needed for better thermal management.

In case of uni-directional time sync, TMU handshake is
initiated by upstream router. In case of bi-directional
time sync, TMU handshake is initiated by downstream router.
In order to handle correctly the case of uni-directional mode,
we avoid changing the upstream router's rate to off,
because it might have another downstream router plugged that is set to
uni-directional mode (and we don't want to change its mode).
Instead, we always change downstream router's rate.
