[PATCH 01/13] ARM: dts: armada-385-linksys: flatten dtsi

From: Ralph Sennhauser
Date: Sun May 21 2017 - 08:51:30 EST


Since the addition of the spi reference two styles are used. Use
references instead of recreating the same structure over and over again.

This helps to distinguish which are changes to the underlying nodes and
which are new additions and helps helps maintainability in general.

Verified the resulting dtb to be binary identical.

Notes:

Care has been taken to change nothing but flatten and sorting
references by name.

Sorting by internal reg no longer makes sense, would be a pain to
maintain order at least.

Comments have at least one level of indentation, they aren't really
meta comments anyway.

The armada-xp-linksys-mamba.dts already makes much better use of this
style.
