[PATCH v6 0/4] of: remove *phandle properties from expanded device tree

[frowand . list]

From: Frank Rowand 

Remove "phandle" and "linux,phandle" properties from the internal
device tree.  The phandle will still be in the struct device_node
phandle field and will still be displayed as if it is a property
in /proc/device_tree.

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 v5:
   - patch 1: populate_properties(), prop_is_phandle was declared
 at the wrong scope and thus was initialized before the for
 loop instead of each time through the loop.  This resulted
 in any property in a node after the phandle property not
 being unflattened.

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().
