[PATCH 2/2] iio: adc: ti_am335x_tscadc: Improve accuracy of measurement

2018-11-18 Thread Vignesh R
When performing single ended measurements with TSCADC, its recommended to set negative input (SEL_INM_SWC_3_0) of ADC step to ADC's VREFN in the corresponding STEP_CONFIGx register. Also, the positive(SEL_RFP_SWC_2_0) and negative(SEL_RFM_SWC_1_0) reference voltage for ADC step needs to be set to V
