14 SPMI PMIC voltage ADC (VADC) provides interface to clients to read
15 voltage. The VADC is a 15-bit sigma-delta ADC.
16 SPMI PMIC5/PMIC7 voltage ADC (ADC) provides interface to clients to read
17 voltage. The VADC is a 16-bit sigma-delta ADC.

74 ADC channel number.
75 See include/dt-bindings/iio/qcom,spmi-vadc.h
76 For PMIC7 ADC, the channel numbers are specified separately per PMIC
77 in the PMIC-specific files in include/dt-bindings/iio/.
82 ADC input of the platform as seen in the schematics.
90 This parameter is used to decrease ADC sampling rate.
93 qcom,pre-scaling:
97 pre-determined ratio and use it for post scaling. It is a pair of
100 down to 1/3 of its value before ADC measurement.
