Subject: [PATCH v2 0/9] platform/chrome: Type-C switch driver and Type-C framework updates
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
v1: https://lore.kernel.org/linux-usb/20220629233314.3540377-1-pmalani@chromium.org/
Changes since v1:
- Changed class name and retimer device type name, and fixed
retimer reference release issue.
