    Hello Vincent,

    I2C_SDA_HOLD
    I2C_FILTER_DEPTH
    SDA_OUTPUT_SETUP 
    These are all used to fine tune the I2C controller behavior within the 953. For most applications they do not need to be adjusted at all from their default values (default I2C behavior is compliant to the I2C standard protocol). 
    CSI-2 Polarity Select
    This one swaps the P/N for each differential pair of the CSI-2 interface. It may be useful if polarity swapping can be used to route the layout more optimally. 
    Best Regards,
    Casey
