Enum pl_adc_num

The enum pl_adc_num contains a list of the constants that refer to available analog-to-digital (ADC) channels, which are mapped to GPIO lines (this mapping can't be altered). For example, ADC channel 0 corresponds to GPIO line 4.

The enum pl_adc_num consists of the following constants:

PL_ADC_NUM_0	ADC channel 0 (mapped to GPIO line 4).
PL_ADC_NUM_1	ADC channel 1 (mapped to GPIO line 5).
PL_ADC_NUM_2	ADC channel 2 (mapped to GPIO line 6).
