Subject: [PATCH 00/11] Apple Silicon USB3 support - TIPD changes

This series contains the required TIPD changes to support USB3 on Apple
Silicon machines and also prepares DisplayPort alternate mode and
Thunderbolt/USB4 support there.

As discussed in the series combining TIPD, DWC3, PHY, and DTS changes
this series contains only the TIPD changes which are already in a pretty
decent shape.

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:
- Added r-b tags from Heikki and Neal
- Addressed Janne's feedback:
  - Updated the tipd commit description to match the dwc3 glue driver
    approach
  - Removed a stale comment left-over from a WIP version and no longer
    required
  - Cleared cd321x->state.data after typec_set_mode is done
  - Removed spurious NULL checks for typec_mux_put and typec_unregister_altmode
  - Call cd321x_connect instead of open-coding almost the same logic
    inside cd321x_interrupt

Best,

Sven
