Subject: [PATCH 19/25] media: ov5647: Implement set_fmt pad operation
Date: Tue, 23 Jun 2020 18:49:11 +0200
Message-ID: <20200623164911.45147-4-jacopo@jmondi.org> (raw)
In-Reply-To: <20200623100815.10674-1-jacopo@jmondi.org>

Now that the driver supports more than a single mode, implement the
.set_fmt pad operation and adjust the existing .get_fmt one to report
the currently applied format.
