Subject: [PATCH 04/10] platform/chrome: cros_ec_typec: Set port alt mode drvdata
Date:   Wed, 28 Dec 2022 00:45:07 +0000

Save the ChromeOS-specific Type-C port info in the port altmodes' driver
data. This makes communication with the ChromeOS EC (Embedded
Controller) easier when alt mode drivers need to send messages to
peripherals.
