13description:
14  MIPID02 has two CSI-2 input ports, only one of those ports can be
15  active at a time. Active port input stream will be de-serialized
16  and its content outputted through PARALLEL output port.
17  CSI-2 first input port is a dual lane 800Mbps per lane whereas CSI-2
18  second input port is a single lane 800Mbps. Both ports support clock
19  and data lane polarity swap. First port also supports data lane swap.
20  PARALLEL output port has a maximum width of 12 bits.
21  Supported formats are RAW6, RAW7, RAW8, RAW10, RAW12, RGB565, RGB888,
22  RGB444, YUV420 8-bit, YUV422 8-bit and YUV420 10-bit.
