From
Subject[PATCH 2/2] of: convert unittest overlay devicetree source to sugar syntax
Date
From: Frank Rowand <frank.rowand@sony.com>

The unittest-data overlays have been pulled into proper overlay
devicetree source files without changing their format. The
next step is to convert them to use sugar syntax instead of
hand coding overlay fragments structure.

A few of the overlays can not be converted because they test
absolute target paths in the overlay fragment. dtc does not
generate this type of target:
overlay_0.dts
overlay_1.dts
overlay_12.dts
overlay_13.dts

Two pre-existing unittest overlay devicetree source files are
also converted:
overlay_bad_phandle.dts
overlay_bad_symbol.dts

Signed-off-by: Frank Rowand <frank.rowand@sony.com>
---
There are checkpatch warnings. I have reviewed them and feel they
can be ignored. They are pre-existing warnings of un-documented
bindings of made up (fake) compatibles in devicetree source for
test overlays.
