Nothing huge in here, just small things:

- thunderbolt memory leaks fixed and new device ids added

- typec power supply fixes to resolve much reported problems about
charging notifications not working anymore

All except the cdc-acm driver quirk addition have been in linux-next
with no reported issues (the quirk patch was applied on Friday, and is
self-contained)"

This includes two fixes for resource leaks that have been around for a
while. Then two fixes for code that was added during v5.10 merge window
and PCI IDs for Intel Tiger Lake-H.

All these have been in linux-next without reported issues.

thunderbolt: Add uaccess dependency to debugfs interface

Some calls in the debugfs interface are made to the linux/uaccess.h header,
but the header is not referenced. So, for x86_64 architectures, this
dependency seems to be pulled in elsewhere, which leads to a successful
compilation. However, on arm/arm64 architectures, it was found to error out
on implicit declarations.

This change fixes the implicit declaration error by adding the
linux/uaccess.h header.

Lots of tiny different things for these subsystems are in here,
including:

- phy driver updates

- thunderbolt / USB 4 updates and additions

- USB gadget driver updates

- xhci fixes and updates

- typec driver additions and updates

- api conversions to various drivers for core kernel api changes

- new USB control message functions to make it harder to get wrong,
as found by syzbot (took 2 tries to get it right)

- lots of tiny USB driver fixes and updates all over the place

All of these have been in linux-next for a while, with the exception
of the last "obviously correct" patch that updated a FALLTHROUGH
comment that got merged last weekend"

thunderbolt: Add debugfs interface

This adds debugfs interface that can be used for debugging possible
issues in hardware/software. It exposes router and adapter config spaces
through files like this:

/sys/kernel/debug/thunderbolt/<DEVICE>/regs
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT1>/regs
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT1>/path
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT1>/counters
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT2>/regs
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT2>/path
/sys/kernel/debug/thunderbolt/<DEVICE>/<PORT2>/counters
...

The "regs" is either the router or port configuration space register
dump. The "path" is the port path configuration space and "counters" is
the optional counters configuration space.

These files contains one register per line so it should be easy to use
normal filtering tools to find the registers of interest if needed.

The router and adapter regs file becomes writable when
CONFIG_USB4_DEBUGFS_WRITE is enabled (which is not supposed to be done
in production systems) and in this case the developer can write "offset
value" lines there to modify the hardware directly. For convenience this
also supports the long format the read side produces (but ignores the
additional fields). The counters file can be written even when
CONFIG_USB4_DEBUGFS_WRITE is not enabled and it is only used to clear
the counter values.
