connection for TX2 4 lanes DSI LCD ?

Hi all,
I know TX2 has 8 data lanes , divided into group A and group B.
Now i want to connect J23 of carrier Board to a 4 lanes DSI LCD.
I know i have to set “nvidia,dsi-n-data-lanes” 4 in panel-x-xxxx-x-x.dtsi file.
should i connect data lanes to group A or group B ? Any other setting in panel-x-xxxx-x-x.dtsi file?



Please use group A first and set the n-data-lanes to 4. Default controller in DSI dts is using the group A.
