Pull devicetree fixes from Grant Likely: "Three more commits needed for v3.17: A bug fix for reserved regions based at address zero, a clarification on how to interpret existence of both interrupts and interrupts-extended properties, and a fix to allow device tree testcases to run on any platform" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: of/irq: Fix lookup to use 'interrupts-extended' property first Enabling OF selftest to run without machine's devicetree of: Allow mem_reserve of memory with a base address of zero

-"interrupts" property or an "interrupts-extended" property. These properties

+Nodes that describe devices which generate interrupts must contain an
+"interrupts" property, an "interrupts-extended" property, or both. If both are
+present, the latter should take precedence; the former may be provided simply
+for compatibility with software that does not recognize the latter. These
+properties contain a list of interrupt specifiers, one per output interrupt. The
+format of the interrupt specifier is determined by the interrupt controller to
+which the interrupts are routed; see section 2 below for details.
Example:
interrupt-parent = <&intc1>;
