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.
