How can I control the ADV7480 to transfer video through CSI in D-PHY burst mode or non burst mode?

Hi,

Please find the below comments,

I didn't find a register to change between burst mode or non-burst mode for CSI?

     ADV7480 specification doesn't contain any register which can differentiate the burst and non burst mode but if you are using IMx processor you can find such register in Nxp document.

And also I can't find out which mode the MAX7480 is working on?

  ADV7480 MIPI CSI-2 output operate in two modes: High Speed and Low Power mode.
Data Lanes:
High speed mode is used to transmit data. Data is transmitted in a differential manner. 
Low Power mode is entered during horizontal and vertical blanking periods. Low power mode is single-ended. 

Data lanes will constantly change from Low Power mode into High Speed mode and corresponding MIPI receiver will need to detect which mode is being output from the ADV748x and modify the termination in the D-PHY accordingly.
Clock Lanes:
Note that after power-up the clock lanes enter high speed mode and will stay in that mode until powered-down. 

Kindly refer "Design Considerations for Connecting Analog Devices MIPI CSI-2 Transmitter to MIPI CSI-2 Receiver .These details are provided by expert in AN-1337 - https://www.analog.com/media/en/technical-documentation/application-notes/AN-1337.pdf

Note: MIPI signals on ADV748x have been set to be compliant to the D-PHY specification and these are specified in the datasheet "MIPI Video output specifications" section.

   These details we can check with MIPI DPHY version 1.00.00 specification to check whether the output data format is compliance with MIPI-CSI2 Specifications

   For our MIPI evaluation we used the MIPI reference termination board available from here:
