The LVDS is used on STM32MP2 as a display interface.

Add the LVDS node.

For the compatible you now need one comaptible per SoC.
It means your compatible should look like : "st,stm32mp251-lvds".
This way, if on the 253 or 255 there is an issue you are able to easily add match data in the driver with compatible "st,stm32mp253-lvds" or "st,stm32mp255-lvds". A prior discussion on this subject has been raised on my V1 of HDP involving Krzysztof and Alexandre :
