Subject: [PATCH v7 25/27] v4l: subdev: add routing & stream config to v4l2_subdev_state
Date: Mon, 24 May 2021 13:44:06 +0300 [thread overview]
Message-ID: <20210524104408.599645-26-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210524104408.599645-1-tomi.valkeinen@ideasonboard.com>
Add routing and stream_configs to struct v4l2_subdev_state. This lets
the drivers to implement V4L2_SUBDEV_FORMAT_TRY support for routing and
the stream configurations.
