Subject: [PATCH v16 02/20] media: add V4L2_SUBDEV_FL_STREAMS
Date: Thu, 15 Dec 2022 14:16:16 +0200	[thread overview]
Message-ID: <20221215121634.287100-3-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20221215121634.287100-1-tomi.valkeinen@ideasonboard.com>

Add subdev flag V4L2_SUBDEV_FL_STREAMS. It is used to indicate that the
subdev supports the new API with multiplexed streams (routing, stream
configs).
