                compatible = "foo,power-controller";
                reg = <0x12340000 0x1000>;

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.
