[PATCH v7 00/63] usb: dwc3: part 1, reset and import from Linux v6.16

Hi,

This is part one of two. It resets the DWC3 driver and imports it up to
Linux v6.16. Part two [3] follows right after this one, it makes the
tree build and work again.

Part one on its own breaks the build for every board that enables DWC3,
and USB gadget stops working. That is expected. The two parts have to go
in together.

The driver was forked from the kernel v3.19-rc1 eleven years ago, in
commit 85d5e7075f33 ("usb: dwc3: add dwc3 folder from linux kernel to
u-boot"). After that almost no kernel changes came back to U-Boot.

Part one is three steps:

1. Re-import xhci-ext-caps.h from v6.16. Marek asked for this one to come
   first, since the dwc3 imports build on it.

2. Restore drivers/usb/dwc3 to a clean v3.19-rc1 state.

3. Import the dwc3 directory once per major kernel version, from v3.19
   up to v6.16. Each commit is a raw snapshot from that kernel. The last
   two patches re-import epautoconf.c and udc-core.c the same way.

The import commits are raw kernel snapshots. This is on purpose. It
makes it easy to see what comes from which kernel version, and to
compare each import with the matching kernel release. The commit
messages say this too.

The branch has both parts [2].

[3] part two, subject: [PATCH v7 00/24] usb: dwc3: part 2, make the
    resynced code work

v6 -> v7:
- Split the series in two. Tom asked for this, so review and iteration
  gets easier. Part one is the reset and the imports, part two makes it
  work.
- Collected Mattijs' Reviewed-by on 18, 27, 33 and 34. Those were the
  four imports he had questions on. Every patch in this part has his tag
  now.
- No code changes in these 63 patches.
- v6 never reached the list in full. My send died in the middle, so the
  cover letter and the last patches went missing.

v5 -> v6:
- Dropped the commits that only touch skipped or preserved files from
  the "Commits imported" lists. Mattijs asked for this on many patches,
  Marek on the v6.0 import.
- Removed a stray "Fixes: b1a3ed068869 (spl: make args file optional in
  falcon mode)" tag from the v4.14 import. Mattijs found it.
- Fixed the "accross" typo in the import commit messages.
- Collected the Reviewed-by tags, 59 from Mattijs and 24 from Simon. The
  code is unchanged on all of them, only the commit messages differ.
- Four imports had no tag from Mattijs: 18, 27, 33 and 34, which were
  17, 26, 32 and 33 in v5. He was right on all four, and what he pointed
  at is gone.
- Moved the xhci-ext-caps.h re-import to the front, Marek asked for that
  on 61/64 in v4. The epautoconf.c and udc-core.c re-imports stayed where
  they were, he did not ask about those. Say if you want them moved too.

Older changes are listed in v5 [1].

Cheers,
Anders
