Subject: Re: [PATCH v4 0/7] usb: typec: Introduce typec-switch binding

I should add:

Series submission suggestions (of course, open to better suggestions too):
- Patches 1-3 can go through the USB repo.
- Patches 4-7 can:
   + also go through the USB repo after the maintainer acks have been
received <or>
   + go through the DRM repo (after creating a branch from USB repo's
usb-next branch after Patches 1-3 have been applied).

(I"ll add the above to the cover letter if there is a v5).

Thanks!
