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. changes since v3: - fix make W=2 warnings in overlay_base.dts and overlay.dts - update the test results in the patch comments to match the .dts changes changes since v2: - test on 4.13-rc1 - remove redundant comments from patch headers of patch 0 and patch 1 - guard make of overlay .dtb files with CONFIG_OF_OVERLAY - guard unittest.c references to overlay .dtb files with CONFIG_OF_OVERLAY changes since v1: - patch 2: Use for_each_child_of_node() instead of open coding, which allowed removing the new function child_by_full_name().
