Subject: [PATCH v3 28/31] adv748x: afe: Implement has_route()
Date: Tue, 5 Mar 2019 19:51:47 +0100 [thread overview]
Message-ID: <20190305185150.20776-29-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20190305185150.20776-1-jacopo+renesas@jmondi.org>
Now that the adv748x subdevice supports internal routing, add an
has_route() operation used during media graph traversal.
