From: Frank Rowand <frank.rowand@xxxxxxxx> Symbols in a loaded overlay are not currently available to subsequently loaded overlays because the properties in the overlay's __symbols__ node are not loaded into the live device tree. Patch 1 is unittests to test patches 2 and 3. Patch 2 fixes a problem discovered while developing patch 3. If a node name in an overlay has a unit-address then the overlay code does not correctly match the node name against an existing node in the live tree. Patch 3 adds the properties in an overlay's __symbol__ node to the overlay changeset. This patch set was created on top of v4.12, with Rob's pull request for 4.13 added (https://lkml.org/lkml/2017/7/6/691). Thus this series should apply on 4.13-rc1 when that becomes available. I will re-test on 4.13-rc1.
