Active port input stream will be de-serialized and its content outputted +through PARALLEL output port. +CSI-2 first input port is a dual lane 800Mbps whereas CSI-2 second input port is +a single lane 800Mbps. Both ports support clock and data lane polarity swap. +First port also supports data lane swap. +PARALLEL output port has a maximum width of 12 bits. +Supported formats are RAW6, RAW7, RAW8, RAW10, RAW12, RGB565, RGB888, RGB444, +YUV420 8-bit, YUV422 8-bit and YUV420 10-bit. + +Required Properties: +- compatible: should be "st,st-mipid02" +- clocks: reference to the xclk input clock. +- clock-names: should be "xclk". +- VDDE-supply: sensor digital IO supply.
