This newly created board-omap35x-pmic.c will be used to provide the board specific regulator hookup code for various TI PMICs (like TWL4030/TPS65950, TPS65023) on different EVMs like OMAP3, AM3517. PMIC initialization routine is called from the board-evm file which will initialize the configured PMIC appropriately.
