Subject: [PATCH v2 22/30] v4l: Add CSI-2 bus configuration to frame descriptors
Date: Fri,  2 Nov 2018 00:31:36 +0100
Message-ID: <20181101233144.31507-23-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20181101233144.31507-1-niklas.soderlund+renesas@ragnatech.se>

From: Sakari Ailus <sakari.ailus@linux.intel.com>

Add CSI-2 bus specific configuration to the frame descriptors. This allows
obtaining the virtual channel and data type information for each stream
the transmitter is sending.
