config ADC
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
config ADC_EXYNOS
bool "Enable Exynos 54xx ADC driver"
help
This enables basic driver for Exynos ADC compatible with Exynos54xx.
It provides:
- 10 analog input channels
- 12-bit resolution
- 600 KSPS of sample rate
config ADC_SANDBOX
bool "Enable Sandbox ADC test driver"
help
This enables driver for Sandbox ADC device emulation.
It provides:
- 4 analog input channels
- 16-bit resolution
- single and multi-channel conversion mode
config SARADC_MESON
bool "Enable Amlogic Meson SARADC driver"
imply REGMAP
help
This enables driver for Amlogic Meson SARADC.
It provides:
- 8 analog input channels
- 1O or 12 bits resolution
- Up to 1MSPS of sample rate
config SARADC_ROCKCHIP
bool "Enable Rockchip SARADC driver"
help
This enables driver for Rockchip SARADC.
It provides:
- 2~6 analog input channels
- 1O or 12 bits resolution
- Up to 1MSPS of sample rate
config STM32_ADC
bool "Enable STMicroelectronics STM32 ADC driver"
depends on ADC && (STM32H7 || ARCH_STM32MP)
help
This enables driver for STMicroelectronics STM32 analog-to-digital
converter (ADC).
A STM32 ADC block can be composed of several individual ADCs.
Each has its own private registers, but shares some resources:
- clock selection and prescaler
- voltage reference
- common registers area.
STM32 ADC driver is composed of:
- core driver to deal with common resources
- child driver to deal with individual ADC resources (declare ADC
device and associated channels, start/stop conversions)
