The ADC can support some channels signal-ended some bits Successive Approximation Register (SAR) A/D Converter, like 6-channel and 10-bit. It converts the analog input signal into some bits binary digital codes.

bool "Enable ADC drivers using Driver Model"
|
|
help
|
|
This enables ADC API for drivers, which allows driving ADC features
|
|
by single and multi-channel methods for:
|
|
- start/stop/get data for conversion of a single-channel selected by
|
|
a number or multi-channels selected by a bitmask
|
|
- get data mask (ADC resolution)
|
|
ADC reference Voltage supply options:
|
|
- methods for get Vdd/Vss reference Voltage values with polarity
|
|
- support supply's phandle with auto-enable
|
|
- supply polarity setting in fdt
