Introduce the OMAP3630 OPPs including the defined OPP tuples. Further information on OMAP3630 can be found here: http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606 OMAP36xx family introduces: VDD1 with 4 OPPs, of which OPP3 & 4 are available only on devices yet to be introduced in 36xx family. Meanwhile, VDD2 has 2 opps. Device Support of OPPs-> |<-3630-600->| (default) |<- 3630-800 ->| (device: TBD) |<- 3630-1000 ->| (device: TBD) H/w OPP-> OPP50 OPP100 OPP-Turbo OPP1G-SB VDD1 OPP1 OPP2 OPP3 OPP4 VDD2 OPP1 OPP2 OPP2 OPP2 Note: a) TI h/w naming for OPPs are now standardized in terms of OPP50, 100, Turbo and SB. This maps as shown above to the opp IDs (s/w term). b) For boards which need custom VDD1/2 OPPs, the opp table can be updated by the board file on a need basis after the omap3_pm_init_opp_table call. The OPPs introduced here are the official OPP table at this point in time.
