From: Frank Rowand <frank.rowand@sony.com>
Remove "phandle" and "linux,phandle" properties from the internal device tree. 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.

Patch 1 is the phandle related changes.
Patches 2 - 4 are minor fixups for issues that became visible while implementing patch 1.
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().
Frank Rowand (4): of: remove *phandle properties from expanded device tree of: make __of_attach_node() static of: be consistent in form of file mode of: detect invalid phandle in overlay
