Hi,
This patch adds optional DT properties for tscadc to set open delay, sample delay and number of averages per sample for each adc channel. Open delay, sample delay and averaging are some of the parameters that affect the sampling rate and accuracy of the tscadc. Decreasing delays and averaging helps to achieve higher sampling rates, while increasing this parameters provides greater accuracy. Hence, this patch provides DT properties to set the initial values for delays and number of averages per sample. User space control via sysfs can be added later.
