Merge tag 'devicetree-fixes-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree fixes from Rob Herring:
- Add empty of_translate_address needed for HiSilicon network driver.
- Fix alignment requirements for CMA regions in DT.
- Fix booting on PPC systems which can't do WARN() early.
- Rename ak4554 binding doc from .c to .txt.
* tag 'devicetree-fixes-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
of: Provide static inline function for of_translate_address if needed
drivers: of: of_reserved_mem: fixup the alignment with CMA setup
of: Print rather than WARN'ing when overlap check fails
dt-bindings: ak4554: extension should be .txt
