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.
