Subject: [PATCH v5 0/7] platform/chrome: Type-C switch driver

v4 of this series was originally merged to the USB maintainer tree, but
there were dependencies from the chrome-platform tree which caused
conflicts in the merge tree, so the chrome specific parts were
reverted [1].

v5 is a resubmission of the series with the Chrome-only parts (since the
USB framework parts were merged successfully).

[1] https://lore.kernel.org/lkml/YtadE201j+dt5jJx@kroah.com/

Original cover letter (with parts relating to USB patches removed):

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.

v4: https://lore.kernel.org/linux-usb/20220711072333.2064341-1-pmalani@chromium.org/

Changes in v5:
- Removed first 2 patches for retimer class support, since those were
  merged in 5.20.
- Added missing ACPI Kconfig to Patch 2/7.
- Updated patches 3/7 and 4/7 to use new function name cros_ec_cmd().
