Subject: [PATCH 0/3] Apple Silicon Type-C PHY

Hi,

As requested in the previous version of the Apple Silicon USB3 support
series this one only contains the changes required for the Type-C PHY.

The generic tunable support inside driver/soc/apple will also be re-used
for Thunderbolt later. I may submit a RFC for that this cycle but I
don't expect that to land before the next one so it should be fine to
just take that commit through the phy tree as well.

Changes since v2 of the combined series:
- Link to v2: https://lore.kernel.org/asahi/20250906-atcphy-6-17-v2-0-52c348623ef6@kernel.org/
- atc.c:
  - Removed a bunch of outdated safety checks from atc.c that were only
    required in a previous version that did not rely on the dwc3-glue
    driver
  - Addressed Philipp's review comments:
    - Added documentation for struct apple_atcphy (and a bunch of other
      things while I was at it)
    - Moved the mutex guard from atcphy_dpphy_configure to atcphy_dp_configure
      since the first one doesn't touch any shared structures or MMIO
- apple,atcphy.yaml:
  - Added a generic apple,tunable definition that uses uint32-matrix
    and refer to that one from the individual tunable properties
  - Adjust the tunable description to make it easier to understand
  - Limited all lines to 80 chars
  - Used > for longer descriptions
  - Fixed some typos
- Picked up r-b tags (thanks!)

Best,

Sven
