Subject: [PATCH v6 22/24] media: uapi: add MEDIA_PAD_FL_MULTIPLEXED flag
Date: Tue, 27 Apr 2021 15:45:21 +0300	[thread overview]
Message-ID: <20210427124523.990938-23-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210427124523.990938-1-tomi.valkeinen@ideasonboard.com>

Add a pad flag to indicate that the pad uses multiplexed streams. A pad
with multiplexed streams won't support pad format configuration and e.g.
VIDIOC_SUBDEV_S_FMT should return -ENOIOCTLCMD.
