Changes in v4:
- Maintainer now listed as Srinivas.
- Example under "soc" to get #address-cells and #size-cells.

Changes in v3:
- Split conversion to yaml into separate patch new in v3.
- Use 'const' for compatible instead of a 1-entry enum.
- Changed filename to match compatible string.
- Add #address-cells and #size-cells to list of properties.
- Fixed up example.

-= Qualcomm QFPROM device tree bindings =
-
-This binding is intended to represent QFPROM which is found in most QCOM SOCs.
-
-Required properties:
-- compatible: should be "qcom,qfprom"
-- reg: Should contain registers location and length
-
-= Data cells =
-Are child nodes of qfprom, bindings of which as described in
-bindings/nvmem/nvmem.txt
-
-Example:
-
-	qfprom: qfprom@...000 {
-		compatible 	= "qcom,qfprom";
-		reg		= <0x00700000 0x8000>;
-		...
-		/* Data cells */
-		tsens_calibration: calib@404 {
-			reg = <0x4404 0x10>;
-		};
-	};
-
-
-= Data consumers =
-Are device nodes which consume nvmem data cells.
-
-For example:
-
-	tsens {
-		...
-		nvmem-cells = <&tsens_calibration>;
-		nvmem-cell-names = "calibration";
-	};
