Subject: [PATCH v2 0/4] of: remove *phandle properties from expanded device tree

From: Frank Rowand <frank.rowand@...y.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 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
