[PATCH v2 0/3] of: overlay: load overlay symbols into live device tree

Show all headers | View raw

From: Frank Rowand <frank.rowand@sony.com>

Symbols in a loaded overlay are not currently available to subsequently
loaded overlays because the properties in the overlay's __symbols__
node are not loaded into the live device tree.

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.

This patch set was created on top of v4.12, with Rob's pull request
for 4.13 added (https://lkml.org/lkml/2017/7/6/691).  Thus this
series should apply on 4.13-rc1 when that becomes available.  I will
re-test on 4.13-rc1.

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().

Frank Rowand (3):
  of: overlay: add overlay unittest data for node names and symbols
  of: overlay: correctly apply overlay node with unit-address
  of: overlay: add overlay symbols to live device tree
