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 per lane 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: shall be "st,st-mipid02" +- clocks: reference to the xclk input clock. +- clock-names: shall be "xclk". +- VDDE-supply: sensor digital IO supply. Must be 1.8 volts. +- VDDIN-supply: sensor internal regulator supply. Must be 1.8 volts. + +Optional Properties: +- reset-gpios: reference to the GPIO connected to the xsdn pin, if any. + This is an active low signal to the mipid02. + +Required subnodes: + - ports: A ports node with one port child node per device input and output + port, in accordance with the video interface bindings defined in + Documentation/devicetree/bindings/media/video-interfaces.txt.
