/**
* omap_bandgap_mcelsius_to_adc() - converts a mCelsius value to ADC scale
* @bg_ptr: struct omap_bandgap pointer
* @temp: value in mCelsius
* @adc: address where to write the resulting temperature in ADC representation
*
* Simple conversion from mCelsius to ADC values. In case the temp value
* is out of the ADC conv table range, it returns -ERANGE, 0 on success.
* The conversion table is indexed by the ADC values.
