16 - Camera Serial Interface (CSI)
31 The CSI is the backend capture unit that interfaces directly with
32 camera sensors over Parallel, BT.656/1120, and MIPI CSI-2 buses.

115 MIPI CSI-2 OV5640 sensor, requires the i.MX6 MIPI CSI-2 receiver. But
117 therefore does not require the MIPI CSI-2 receiver, so it is missing in
140 This is the MIPI CSI-2 receiver entity. It has one sink pad to receive
141 the MIPI CSI-2 stream (usually from a MIPI CSI-2 camera sensor). It has
142 four source pads, corresponding to the four MIPI CSI-2 demuxed virtual
146 This entity actually consists of two sub-blocks. One is the MIPI CSI-2
147 core. This is a Synopsys Designware MIPI CSI-2 core. The other sub-block
148 is a "CSI-2 to IPU gasket". The gasket acts as a demultiplexer of the
167 MIPI CSI-2 virtual channels from imx6-mipi-csi2 entity. They have a
168 single source pad that routes to a CSI (ipuX_csiY entities).
