The structure `tb_eeprom_ctl` is used to show the bits accessed when
reading/writing EEPROM.
As this structure is specified in the USB4 spec as `VSC_CS_4` update
the names and use of members to match the specification. This should not
change anything functionally.

The USB4 1.0 specification outlines the `cap_plug_events` structure as
`VSC_CS_1`. This shows that 4 bits of `VSC_CS_1` are TBT3 compatible in
USB4, but TBT3 controllers also support disabling XHCI.
Update the names and comments to more closely match the specification.
This should not change anything functionally.

The USB4 specification doesn't make any requirements that reading
a device router's DROM is needed for the operation of the device.
Other connection manager solutions don't necessarily read it or gate
the usability of the device on whether it was read.
So make failures when reading the DROM show warnings but not
fail the initialization of the router.

Routers might not have a UID set if the DROM read failed during
initialization previously.
Normally upon resume the UID is re-read to confirm it's the same
device connected.
* If the DROM read failed during init but then succeeded during
resume it could either be a new device or faulty device
* If the DROM read failed during init and also failed during resume
it might be a different device plugged in all together.
Detect this situation and prevent re-using the same configuration in
these cirucmstances.

Currently DROM reads are only retried in the case that parsing failed.
However if the size or CRC fails, then there should also be a retry.
This helps with reading the DROM on TBT3 devices connected to AMD
Yellow Carp which will sometimes fail on the first attempt.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
Simplify code and remove some dead code accordingly.
While at it, include directly <linux/dma-mapping.h> instead on relying on
indirect inclusion.

In this patch we add enabling of CL0s - a low power state of the link.
Low power states (called collectively CLx) are used to reduce
transmitter and receiver power when a high-speed lane is idle. For now,
we add support only for first low power state: CL0s. We enable it, if
both sides of the link support it, and only for the first hop router.
(i.e. the first device that connected to the host router). This is
needed for better thermal management.

Sometimes when plugging in a USB4 device we might see following error:
thunderbolt 1-0:3.1: runtime PM trying to activate child device 1-0:3.1 but parent (usb4_port3) is not active

If the boot firmware implements connection manager of its own it may not
create the paths in the same way or order we do. For example it may
create first PCIe tunnel and then USB3 tunnel. When we restore our
tunnels (first de-activating them) we may be doing that over completely
different tunnels and that leaves them possibly non-functional. For this
reason we re-use the tunnel discovery functionality and find out all the
existing tunnels, and tear them down. Once that is done we can restore
our tunnels.

If protocol tunnels are already up when the driver is loaded, for
instance if the boot firmware implements connection manager of its own,
runtime PM reference count of the consumer devices behind the tunnel
might have been increased already before the device link is created but
the supplier device runtime PM reference count is not. This leads to a
situation where the supplier (the Thunderbolt driver) can runtime
suspend even if it should not because the corresponding protocol tunnel
needs to be up causing the devices to be removed from the corresponding
native bus.
Prevent this from happening by making both sides of the link runtime PM
active briefly. The pm_runtime_put() for the consumer (PCIe
root/downstream port, xHCI) then allows it to runtime suspend again but
keeps the supplier runtime resumed the whole time it is runtime active.

The tb_test_credit_alloc_all() function had a huge number of
KUNIT_ASSERT() statements, all of which (though the magic of many many
layers of inscrutable macros) ended up allocating and initializing
various test assertion structures on the stack.
Don't do that. The kernel stack isn't infinite, and we have compiler
warnings (now errors) for the case where a stack frame grows too large.
Like it did here, by not an inconsiderable margin:
drivers/thunderbolt/test.c: In function ‘tb_test_credit_alloc_all’:
drivers/thunderbolt/test.c:2367:1: error: the frame size of 4500 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
2367 | }
| ^
Solve this similarly to the lib/test_scanf case: split out the tests
into several smaller functions, each just testing one particular tunnel
credit allocation.
This makes the i386 allyesconfig build work for me again.

In tb_switch_default_link_ports(), while linking of ports,
only odd-numbered ports (1,3,5..) are considered and even-numbered
ports are not considered.
AMD host router has lane adapters at 2 and 3 and link ports at adapter 2
is not considered due to which lane bonding gets disabled.
Hence added a fix such that all ports are considered during

Adapter 0 is the control adapter and as per USB4 spec in section 2.2.6.2
control Adapters do not have an adapter configuration space.
For this reason skip reading adapter config space in tb_port_init() when
the port number is 0. This actually simplifies the rest of the function
as we don't need to check for the port->port == 0 anymore.
While there drop the extra empty line at the end of the function.

For security reasons, we would like to monitor and track when the
Thunderbolt devices are authorized and deauthorized (i.e. when the
Thunderbolt sysfs "authorized" attribute changes). Currently the
userspace gets a udev change notification when there is a change, but
the state may have changed (again) by the time we look at the authorized
attribute in sysfs. So an authorization event may go unnoticed. Thus
make it easier by informing the actual change (new value of authorized
attribute) in the udev change notification.
The change is included as a key value "authorized=<val>" where <val>
is the new value of sysfs attribute "authorized", and is described at
Documentation/ABI/testing/sysfs-bus-thunderbolt under
/sys/bus/thunderbolt/devices/.../authorized.

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

Partially revert "thunderbolt: test: Remove some casts which are no
longer required". It turns out that typeof() doesn't support bitfields,
so these still need to be cast to the appropriate enum.
The only mention of typeof() and bitfields I can find is in the proposal
to standardise them:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2619.htm

With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in the thunderbolt KUnit tests are no longer
required.
Remove the unnecessary casts, making the conditions clearer.

DROM for USB4 host/device has a shorter header than Thunderbolt DROM
header. This patch addresses host/device with USB4 DROM (According to spec:
Universal Serial Bus 4 (USB4) Device ROM Specification, Rev 1.0, Feb-2021).
While there correct the data_len field to be 12 bits and rename
__unknown1 to reserved following the spec.

Alder Lake has the same integrated Thunderbolt/USB4 controller as
Intel Tiger Lake. By default it is still using firmware based connection
manager so we can use most of the Tiger Lake flows.
Add the Alder Lake PCI IDs to the driver list of supported devices.
