Subject: [PATCH 03/19] media: adv748x: Use V4L2 streams
Date: Tue, 30 Apr 2024 12:39:39 +0200 [thread overview]
Message-ID: <20240430103956.60190-4-jacopo.mondi@ideasonboard.com> (raw)
In-Reply-To: <20240430103956.60190-1-jacopo.mondi@ideasonboard.com>
Initialize the CSI-2 subdevice with the V4L2_SUBDEV_FL_STREAMS flag
and initialize a simple routing table by implementing the .init_state()
operation.
