The more I look at this, the more wrong it is :/

 From the new binding documentation,

+	A cpus node must define the following properties:
+
+	- #address-cells
+		Usage: required
+		Value type: <u32>
+		Definition: must be set to 1 for 32-bit systems and 2 for
+			    64-bit systems
+	- #size-cells
+		Usage: required
+		Value type: <u32>
+		Definition: must be set to 0

...

+- cpu node
+
+	Description: Describes a CPU in an ARM based system
+
+	PROPERTIES
+
+	- device_type
+		Usage: required
+		Value type: <string>
+		Definition: must be "cpu"

Three required properties that aren't present in the patch.

cpus {
     #size-cells = <0>;
     #address-cells = <1>;

     cpu {
         device_type = "cpu"
         compatible = "arm,arm926";
     };
};
