Don't be put off by the weird patch

Afterwards introduce of_node_is_initialized & of_node_is_attached that
query the underlying kobject about the state (attached means kobj

Using that make sure the lifecycle of the tree is correct at all

Introduce support for dynamic device tree resolution.
Using it, it is possible to prepare a device tree that's
been loaded on runtime to be modified and inserted at the kernel
live tree.

$ echo -0 device-tree-overlay-status
Removes the overlay.
Note that this seldom works on most platforms since platform_device
removal is something that almost never works without extra patches.

Changes in V2:
* Removal of any bits related to a specific board (beaglebone).
* Introduced a platform agnostic interface using /proc/device-tree-overlay
* Various bug fixes related to i2c device handling have been squashed in.

Pantelis Antoniou (5):
OF: Introduce device tree node flag helpers.
OF: Clear detach flag on attach
OF: export of_property_notify
OF: Export all DT proc update functions
OF: Introduce utility helper functions
drivers/of/Makefile | 2
When attaching a node always clear the detach flag. Without this change
the sequence detach, attach fails.

This patchset introduces a number of fixes that are required
for the subsequent patches that add DT overlays support.
Most of them are trivial, adding small bits that are missing,
or exporting functions that were private before.
