 Example:

                compatible = "foo,power-controller";
                reg = <0x12340000 0x1000>;
                #power-domain-cells = <1>;

+               power-off-latency = <250000>;
This assumes every power domain within a power controller has the
same latencies? That isn't always true. This should be an array
of values corresponding to the number of power domains if
#power-domain-cells is 1, or just one value if the cell count is
0.
Thanks, you're right. Will update.

However, I'd still like to allow just one value in the #power-domain-cells = <1>
case if the latencies are the same. Is that OK for you?

Thanks again.

Gr{oetje,eeting}s,
