Lots of activity in the devicetree code for v3.18. Most of it is related
to getting all of the overlay support code in place, but there are other
important things in there.
There are a few trivial merge conflicts. They shouldn't give you any
trouble.
Highlights:
- OF_RECONFIG notifiers for SPI, I2C and Platform devices. Those
subsystems can now respond to live changes to the device tree.
- CONFIG_OF_OVERLAY method for applying live changes to the device tree
- Removal of the of_allnodes list. This used to be used to iterate over
all the nodes in the device tree, but it is unnecessary because the
same thing can be done by iterating over the list of child pointers.
Getting rid of of_allnodes saves some memory and avoids the
possibility of of_allnodes being sorted differently from the child
lists.
- Support for retrieving original DTB blob via sysfs. Needed by kexec.
- More unittests
- Documentation and minor bug fixes
