I see your point in http://marc.info/?l=linux-omap&m=129847126805656&w=2
"Check the definition of omap_volt_pmic_info and omap_volt_data.
Just to "hack" support we can fill *don't care* values for the
fields not supported and wrap processing under if (cpu_is_....())
checks; but this doesn't appear to be a good solution"
PMIC specific data:

SoC specific data + PMIC limits:

I dont like the following at all!

SOC specific

Yeah they ought to be split properly IMHO.
