How to set cil_settletime in CSI?

Hi,
our mipi board connect to tx2,
CSI output:the CSI speed/lane is 200MHz, the Tclk_prepare+Tclk_zero is 394ns…
the default value of cil_settletime is 23, we can not capture mipi data if use default value…
How to calculate cil_settletime value?

Check below document for the formula. Also you can set it as 0 for auto calculated by driver.

In my case, Tclk_prepare+Tclk_zero = 394ns,
which parameter in dts is related to this?
