    s3c_adc_battery: Average over more than one adc sample · 34aed73d
    Heiko Stübner authored
    Some sources for adc battery information provide only inaccurate results
    where the read value differs from the real value with positive and negative
    offsets. For such sources it can be more accurate to collect two or more
    value sample and use the average of all collected values.
    This patch adds pdata options volt_samples, current_samples and
    backup_volt_samples to specifiy the number of samples to collect,
    reads the specified number of samples and calculates the average of those.
    For unset sample-number-values a default of 1 is assumed.
