    mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversion · a5055d5d
    Pali Rohár authored
    Driver twl4030-madc has hardcoded channel types (10 - battery current,
    1 - battery temperature) and also conversation data in variable
    twl4030_divider_ratios. These hardcoded channels are incorrect for
    Nokia RX-51 board (where is channel 0 - battery temperature).
    For Nokia RX-51 there is rx51_battery power_supply driver which reporting
    battery information via twl4030_madc_conversion. But this driver needs
    raw values (not converted via some hardcoded functions). So this patch
    adding new parameter "raw" to struct twl4030_madc_request which tell
    twl4030-madc driver to not convert values, but rather return raw.
