+description:
+ The ISP3.0 SENINF is the CSI-2 and parallel camera sensor interface found in
+ multiple MediaTek SoCs. It can support up to three physical CSI-2
+ input ports, configured in DPHY (2 or 4 data lanes) or CPHY depending on the soc.
+ On the output side, SENINF can be connected either to CAMSV instance or
+ to the internal ISP. CAMSV is used to bypass the internal ISP processing
+ in order to connect either an external ISP, or a sensor (RAW, YUV).
