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.

61 Represents the external channels which are connected to the ADC.
62 For compatible property "qcom,spmi-vadc" following channels, also known as
72 ADC channel number.
73 See include/dt-bindings/iio/qcom,spmi-vadc.h
74 For PMIC7 ADC, the channel numbers are specified separately per PMIC
75 in the PMIC-specific files in include/dt-bindings/iio/.
79 ADC input of the platform as seen in the schematics.
87 This parameter is used to decrease ADC sampling rate.
90 qcom,pre-scaling:
94 pre-determined ratio and use it for post scaling. It is a pair of
97 down to 1/3 of its value before ADC measurement.
