Merge tag 'devicetree-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:

 - fix sparse warnings in drivers/of/

 - add more overlay unittests

 - update dtc to v1.4.4-8-g756ffc4f52f6. This adds more checks on dts
   files such as unit-address formatting and stricter character sets for
   node and property names

 - add a common DT modalias function

 - move trivial-devices.txt up and out of i2c dir

 - ARM NVIC interrupt controller binding

 - vendor prefixes for Sensirion, Dioo, Nordic, ROHM

 - correct some binding file locations

+* ARM Nested Vector Interrupt Controller (NVIC)
+
+The NVIC provides an interrupt controller that is tightly coupled to
+Cortex-M based processor cores.  The NVIC implemented on different SoCs
+vary in the number of interrupts and priority bits per interrupt.
+
+Main node required properties:
+
+- compatible : should be one of:
+        "arm,v6m-nvic"
+        "arm,v7m-nvic"
+        "arm,v8m-nvic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source.  The type shall be a <u32> and the value shall be 2.
+
+  The 1st cell contains the interrupt number for the interrupt type.
+
+  The 2nd cell is the priority of the interrupt.
+
+- reg : Specifies base physical address(s) and size of the NVIC registers.
+  This is at a fixed address (0xe000e100) and size (0xc00).
+
+- arm,num-irq-priority-bits: The number of priority bits implemented by the
+  given SoC
+
+Example:
+
+        intc: interrupt-controller@e000e100 {
+                compatible = "arm,v7m-nvic";
+                #interrupt-cells = <2>;
+                #address-cells = <1>;
+                interrupt-controller;
+                reg = <0xe000e100 0xc00>;
+                arm,num-irq-priority-bits = <4>;
+        };
