# Infineon M0S8PASS SAR ADC configuration options

config ADC_INFINEON_SAR
bool "Infineon M0S8PASS SAR ADC driver"
default y
depends on DT_HAS_INFINEON_M0S8PASS_SAR_ADC_ENABLED
select ADC_CONFIGURABLE_INPUTS
select USE_INFINEON_ADC
help
Enable M0S8PASS SAR ADC driver for Infineon devices.

config ADC_INFINEON_SAR_SARSEQ_SWITCHING
bool "Use SARSEQ hardware switch control"
default y
depends on ADC_INFINEON_SAR
help
Enable SARSEQ (hardware sequencer) control of SAR ADC input switches.
If disabled, the driver relies on firmware-controlled switches only.
