The phandle will still be in the struct device_node phandle field. This is to resolve the issue found by Stephen Boyd [1] when he changed the type of struct property.value from void * to const void *. As a result of the type change, the overlay code had compile errors where the resolver updates phandle values. [1] http://lkml.iu.edu/hypermail/linux/kernel/1702.1/04160.html Patch 1 is the phandle related changes. Patches 2 - 4 are minor fixups for issues that became visible while implementing patch 1. Changes from v4: - rebase on 4.12-rc1 - Add reason for "" in of_attach_node() - Simplify and consolidate phandle detection logic in populate_properties(). This results in a change of behaviour, the value of property "ibm,phandle" will no longer override the value of properties "phandle" and "linux,phandle". Changes from v3: - patch 1: fix incorrect variable name in __of_add_phandle_sysfs(). Problem was reported by the kbuild test robot Changes from v2: - patch 1: Remove check in __of_add_phandle_sysfs() that would not add a sysfs entry if IS_ENABLED(CONFIG_PPC_PSERIES) Changes from v1: - Remove phandle properties in of_attach_node(), before attaching the node to the live tree. - Add the phandle sysfs entry for the node in of_attach_node(). - When creating an overlay changeset, duplicate the node phandle in __of_node_dup().
