This series introduces a retimer class to the USB Type-C framework,
It also introduces a Chrome EC (Embedded Controller) switch driver which
registers the aforementioned retimer switches as well as mode-switches.

Patch 1 and 2 introduce the retimer class and associated functions to
the Type-C common code.

Patches 3-7 add the cros-typec-switch driver.

Patches 8-9 update cros-ec-typec to get and use retimer switch handles.

Submission suggestion (as always, open to better suggestions):
- Patch 1 and 2 can go through the USB repo.
- Patch 3-9 can go through the chrome-platform repo. Since they depend
  on patches 1 and 2, we can create an "topic branch" off of usb-next
  once Patch 1 and 2 are submitted, and then apply Patches 3-9 on top
  of that "topic branch" before merging it back into chrome-platform's
  for-next branch

v3: https://lore.kernel.org/linux-usb/20220707222045.1415417-1-pmalani@chromium.org/

Changes since v3:
- Updated Commit message of Patch 1 to mention that no new
  class-specific sysfs files are being created.

Changes since v2:
- Fixed missing "static" declarations, and removed newlines from
  function signatures.

Changes since v1:
- Changed class name and retimer device type name, and fixed
  retimer reference release issue.

That's a mess, I can just take all of them into my tree if you want.

That works for me. Thanks for taking Patch 1 and 2; it should be fine
to apply the rest of the patches to your tree too.
