Merge tag 'devicetree-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux into next
Pull DeviceTree updates from Rob Herring:
- Another round of clean-up of FDT related code in architecture code.
This removes knowledge of internal FDT details from most
architectures except powerpc.
- Conversion of kernel's custom FDT parsing code to use libfdt.
- DT based initialization for generic serial earlycon. The
introduction of generic serial earlycon support went in through the
tty tree.
- Improve the platform device naming for DT probed devices to ensure
unique naming and use parent names instead of a global index.
- Fix a race condition in of_update_property.
- Unify the various linker section OF match tables and fix several
function prototype errors.
- Update platform_get_irq_byname to work in deferred probe cases.
- 2 binding doc updates
