Subject: [PATCH v3 3/9] platform/chrome: Add Type-C mux set command definitions
Date: Thu,  7 Jul 2022 22:20:10 +0000	[thread overview]
Message-ID: <20220707222045.1415417-4-pmalani@chromium.org> (raw)
In-Reply-To: <20220707222045.1415417-1-pmalani@chromium.org>

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]
