Hi,

I didn't spot a memory node here or in the dtsi. Does the FW/bootloader
create one?

+		#size-cells = <2>;

Why have this empty node?

Please ad an interrupt-affinity property, as described in
Documentation/devicetree/bindings/arm/pmu.txt.

I believe that the second entry should be 0x2000 in length.

Thanks,
Mark.
