The monaco-ac EVK is a new board variant which shares the majority of
its hardware description with the existing monaco-evk board.

No, this is not a good reason. Is there a common PCB? There was a long
discussion for it for the Hamoa / Purwa EVK.

PCB is not common for these 2 boards.

Also, not sure if I mis-understood you - You had mentioned to have a
common file for both the variants [1] in the earlier version of patch
hence refactored it this way.

There was an explicit question if PCB is the same as a prerequisite for
the unification of DTS

Thanks for the clarification.

This was discussed in the earlier v2 [1] — even though the PCB is not
common, the majority of the hardware blocks and their wiring are
functionally identical between monaco-evk and monaco-ac-evk, with only
difference in H/W being 4 PMIC in monaco-evk v/s 2 PMIC on monaco-ac-evk
and the rail which is supplied to the SDHC controller.

The intent here is to avoid duplication across the two boards rather
than imply a shared PCB, similar to what was discussed earlier.

If this approach is still not acceptable without a common PCB, can I
drop the refactoring and keep the DTS files fully separate ?

In preparation for adding this variant, extract the common hardware
nodes from monaco-evk.dts into a new shared monaco-evk-common.dtsi
include file, and update monaco-evk.dts to include it and keep only
board-specific overrides.

No functional change intended.
