This should not affect other users of DTS. J784S4 already has this
change and it serves as a validation that DT nodes are compatible
with other projects (for example uboot driver handles it).
Other SoCs are being modified with taking J784S4 as a working reference.

Considering this, do I still need to add something? Or is it okay
since I am not exactly affecting other projects?
Should I add something along the lines of "similar to j784s4...."?


Warm Regards,
Jayesh
