- index
	Usage: Required
	Value type: <u32>
	Definition: It represents the idle state index.
		    The index must be given an increasing
		    value = {0, 1, ....}, starting from 0, with higher
		    values implying less power consumption.
		    Indices must be unique as seen from a cpu
		    perspective, ie phandles in the cpu nodes [1]
		    cpu-idle-states array property are not allowed to
		    point at idle state nodes having the same index
		    value.

Ack ?

I will post a v5, should be final.
