[PATCH 0/9] platform/chrome: Type-C switch driver and Type-C framework updates

[Prashant Malani]

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
