CONFIG_SUN4I_GPADC: Allwinner A10/A13/A31 and similar GPADCs driver

General informations

The Linux kernel configuration item CONFIG_SUN4I_GPADC has multiple definitions:

Allwinner A10/A13/A31 and similar GPADCs driver found in drivers/iio/adc/Kconfig

The configuration item CONFIG_SUN4I_GPADC:

• prompt: Allwinner A10/A13/A31 and similar GPADCs driver
• type: tristate
• depends on: ( CONFIG_IIO ) && ( CONFIG_MFD_SUN4I_GPADC || CONFIG_MACH_SUN8I ) && ( CONFIG_THERMAL || ! CONFIG_THERMAL_OF )
• defined in drivers/iio/adc/Kconfig
• found in Linux kernels: 6.6–6.12, 6.13-rc+HEAD
• modules built: sun4i-gpadc-iio

Help text

Say yes here to build support for Allwinner (A10, A13 and A31) SoCs GPADC. This ADC provides 4 channels which can be used as an ADC or as a touchscreen input and one channel for thermal sensor.

The thermal sensor slows down ADC readings and can be disabled by disabling THERMAL_OF. However, the thermal sensor should be enabled by default since the SoC temperature is usually more critical than ADC readings.

To compile this driver as a module, choose M here: the module will be called sun4i-gpadc-iio.
