I used the original 3.8 kernel's dts from TI. And the cpu node (I've modified
to move the timer node outside it) is like:

	cpus {
		cpu@0 {
			device_type = "cpu";
			compatible = "arm,cortex-a15";
			reg = <0x0>;
		};
		cpu@1 {
			device_type = "cpu";
			compatible = "arm,cortex-a15";
			reg = <0x1>;
		};
	};

And I checked the latest git tree I've used, it is:

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

		cpu@0 {
			device_type = "cpu";
			compatible = "arm,cortex-a15";
			reg = <0x0>;
		};
		cpu@1 {
			device_type = "cpu";
			compatible = "arm,cortex-a15";
			reg = <0x1>;
		};
	};

I'll check if the missing address-cells and size-cells caused my
issues.

Thanks.
