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
