linux-vybrid_public/Documentation/devicetree/bindings/resource-names.txt

Some properties contain an ordered list of 1 or more datum which are
normally accessed by index.  However, some devices will have multiple
values which are more naturally accessed by name.  Device nodes can
include a supplemental property for assigning names to each of the list
items.  The names property consists of a list of strings in the same
order as the data in the resource property.

The following supplemental names properties are defined.

Resource Property	Supplemental Names Property
-----------------	---------------------------
reg			reg-names
clocks			clock-names
interrupts		interrupt-names

Usage:

The -names property must be used in conjunction with the normal resource
property. If not it will be ignored.

Examples:

l4-abe {
	compatible = "simple-bus";
	#address-cells = <2>;
	#size-cells = <1>;
	ranges = <0 0 0x48000000 0x00001000>, /* MPU path */
		 <1 0 0x49000000 0x00001000>; /* L3 path */
	mcasp {
		compatible = "ti,mcasp";
		reg = <0 0x10 0x10>, <0 0x20 0x10>,
		      <1 0x10 0x10>, <1 0x20 0x10>;
		reg-names = "mpu", "dat",
			    "dma", "dma_dat";
	};

	timer {
		compatible = "ti,timer";
		reg = <0 0x40 0x10>, <1 0x40 0x10>;
		reg-names = "mpu", "dma";
	};
};


usb {
	compatible = "ti,usb-host";
	reg = <0x4a064000 0x800>, <0x4a064800 0x200>,
	      <0x4a064c00 0x200>;
	reg-names = "config", "ohci", "ehci";
};
