- 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.
