Subject: [PATCH 06/10] platform/chrome: cros_ec_typec: Move structs to header
Date:   Wed, 28 Dec 2022 00:45:09 +0000
Message-Id: <20221228004648.793339-7-pmalani@chromium.org>
In-Reply-To: <20221228004648.793339-1-pmalani@chromium.org>
References: <20221228004648.793339-1-pmalani@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Move ChromeOS Type-C structs into their own header, so they can be
referenced by other files which can be added to the same module.

No functional changes introduced by this patch.
