+ ti,chan-step-opendelay: List of open delays for each channel of
+ ADC in the order of ti,adc-channels. The
+ value corresponds to the number of ADC
+ clock cycles to wait after applying the
+ step configuration registers and before
+ sending the start of ADC conversion.
+ Maximum value is 0x3FFFF.
+ ti,chan-step-sampledelay: List of sample delays for each channel
+ of ADC in the order of ti,adc-channels.
+ The value corresponds to the number of
+ ADC clock cycles to sample (to hold
+ start of conversion high).
+ Maximum value is 0xFF.
+ ti,chan-step-avg: Number of averages to be performed for each
+ channel of ADC. If average is 16 then input
+ is sampled 16 times and averaged to get more
+ accurate value. This increases the time taken
+ by ADC to generate a sample. Valid range is 0
+ average to 16 averages. Maximum value is 16.
