I mean the point between the v1.1 maybe this should be v11 or v1_1.

Can you provide me the link please?

I know that kind of hierarchy ;)

The vgen3 regulator node can be available in the imx6qdl-colibri.dtsi even
if it isn't used on the v1.0. The comment should highlight that.

The last dts node will override/expand the underlying nodes. The
'no-1-8-v' should be moved to the v1.0 dts or you need to add
'/delete-property/ no-1-8-v' to your v1.1 dts. All other properties will
exapand the node.

Pleas check my above comments. Your patche duplicates a lot of code
which is common.

Please check my above comments.
