Hi expert

       I'm debugging adv7282m chip,And use the following set of parameters. The CVBS Images  can be displayed on our lcd screens.

But "frame dropped " issue will occur on our  receiving plarform,I want to decrease the MIPI  rate(DP0/DP1,CLKP,CLKN) and have a try.

       I have some question as follows:

      1.What value the mipi data(dp0/dp1) output rate is  when using the following parameters?

       2.How  to decrease the MIPI  rate(DP0/DP1,CLKP,CLKN)?Could you tell me in details?
