OMAP3+: PM: DVFS: Scale dependent domains to existing OPP
Currently dependent domain is scaled to:
- dependent voltage that is got from voltage dependency table.
- frequency that is got from OPP found for dependent voltage.
OPP for dependent voltage is found by _volt_to_opp() function
which looks for OPP with equal or _greater_ voltage.
So if there is no OPP with exact voltage (or this OPP is disabled),
then frequency from OPP with higher voltage will be used.
As a result device will run at not supported combination of frequency and voltage.
This may lead to instabilities.
This patch scales dependent domain to a correct voltage-frequency tuple,
by using both frequency and voltage from the matched OPP.
