Subject: [PATCH v2 24/30] adv748x: csi2: add translation from pixelcode to CSI-2 datatype
Date: Fri, 2 Nov 2018 00:31:38 +0100 [thread overview]
Message-ID: <20181101233144.31507-25-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20181101233144.31507-1-niklas.soderlund+renesas@ragnatech.se>
Prepare to implement frame descriptors to support multiplexed streams by
adding a function to map pixelcode to CSI-2 datatype. This is needed to
properly be able to fill out the struct v4l2_mbus_frame_desc.
