Subject: [PATCH 02/20] v4l2-subdev.h: add pad and stream aware s_stream
Date: Fri, 11 Aug 2017 11:56:45 +0200	[thread overview]
Message-ID: <20170811095703.6170-3-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20170811095703.6170-1-niklas.soderlund+renesas@ragnatech.se>

To be able to start and stop individual streams of a multiplexed pad the
s_stream operation needs to be both pad and stream aware. Add a new
operation to pad ops to facilitate this.
