Still wrong form multiple points of view:
1. Not logical, we never expect such entry in top level bindings,
2. Same board or different? If same, how is it possible to have two
different SoCs (not modules!) in the same board? These are different
boards. Or maybe this uses some SoM, but your commit msg explained
nothing about this.

You have entire commit msg to explain the hardware. Use it, so you don't
get such questions.

The code above: NAK
