The data struct is used to support different PMIC chip types. It contains the chip type and the data (e.g. registers addresses, adc multiplier) which is different for twl6030 and twl6032. Replaced some hardcoded values with the structure vars. Based on Balaji T K <balajitk@ti.com> patches for TI u-boot. Signed-off-by: Oleg Kosheliev <oleg.kosheliev@ti.com>
