This patch registers the TWL4030 PMIC specific informtion with the voltage driver. Failing this patch the voltage driver is unware of the formula to use for vsel to voltage and vice versa conversion and lot of other PMIC dependent parameters. This file is based on the arch/arm/plat-omap opp_twl_tpl.c file by Paul Walmsley. The original file is replaced by this file.
