+ *  TBD:
+ *      1. Make # power states dynamic.
+ *      2. Support duty_cycle values that span bit 4.
+ *      3. Optimize by having scheduler determine business instead of
+ *         having us try to calculate it here.
+ *      4. Need C1 timing -- must modify kernel (IRQ handler) to get this.
