    Hi,

    I am using a board with A31 processor. I am trying to interface a HDMI to CSI-2 converter IC to the processor. I see that the MIPI DPHY debug registers indicate different values of data once I have configured the converter IC. But I do not see any data in the MIPI CSI registers. Any suggestions?
    Also, I see a GPIO PE16 (MIPI-CSI-MCLK). What is this clock? Is it required for MIPI-CSI module normal operation? What must be its value?
    Thanks in advance.
