This looks like regular override-by-label instead of full path.
Unfortunately change of the indentation causes difficulties to find the
real difference - if there is such. Can you split it into separate patch?
The point is that override-by-label should have zero effect on
functionality and produce same dtb. This is easy to compare with
dtx_diff or fdt-decompile but if you mix it with other changes, the
comparison is not straight-forward.

Same here and in other places. Actually here a sneaky change is visible
- different property.
