what are the changes i have to do in dts files for CSI2-MIPI work

[srinivas_123]

I am using the imx8mplus evk board. On my board, I have CSI1-MIPI and CSI2-MIPI camera interfaces .

By default, CSI1-MIPI is enabled and CSI2-MIPI is disabled in dts files . I required the CSI2-MIPI interface to work. so I enabled the below places in dts file. After enabled also still it is not working. how to approach it, am I doing the correct  or not

I want to make CSI2-MIPI has to work. How to approach.
