I want to change the imx274-sensor from CSI-LANE2 mode to CSI-LANE4,I made the following two modifications according to the nvidia official documents，but it doesn’t work：
first operate：change num_lanes fron 2 to 4
image
second operate ：change bus-width fron 2 to 4

May I ask whether it needs any extra operation to make it work properly？

You need to get the sensor REG configure for 4 lanes from Sony too.
