Subject: [PATCH v2 3/9] platform/chrome: Add Type-C mux set command definitions
Date:   Wed,  6 Jul 2022 17:15:07 +0000

Copy EC header definitions for the USB Type-C Mux control command from
the EC code base. Also pull in "TBT_UFP_REPLY" definitions, since that
is the prior entry in the enum.

These headers are already present in the EC code base. [1]
