Subject: [PATCH 2/9] usb: typec: Add retimer handle to port
Date:   Wed, 29 Jun 2022 23:32:20 +0000
Message-Id: <20220629233314.3540377-3-pmalani@chromium.org>

Similar to mux and orientation switch, add a handle for registered
retimer to the port, so that it has handles to the various switches
connected to it.
