Subject: [PATCH usb-next v2 0/5] Apple Silicon USB3 support - dwc3

Hi,

As discussed in v2 of the combined Apple Silicon USB3 support series
this one only contains the dwc3 changes without the DTS changes.

Changes since v1 of the dwc3-only series:
- Link to v1: https://lore.kernel.org/r/20251013-b4-aplpe-dwc3-v1-0-12a78000c014@kernel.org
- Rebased on usb-testing
- Fixed a trivial merge conflict in glue.h regarding struct dwc3_properties
- Added DWC3_DEFAULT_PROPERTIES to dwc3-apple.c
- Added Thinh's Acks (thanks!)

Link to v2 of the combined series: https://lore.kernel.org/asahi/20250906-atcphy-6-17-v2-0-52c348623ef6@kernel.org/
Changes since v2 of that series:
- Documented all functions in glue.h
- Fixed a typo in the example for the dt-bindings
- Added detailed documentation about how the dwc3 hardware needs to be
  driven on this platform to the glue driver
- Renamed dwc3_apple.mode to state and folded in the probe check into
  the new DWC3_APPLE_PROBE_PENDING state
- Collected tags

Best,

Sven
