- Place ISR version ADC oneshot mode read function into IRAM.

- Ensure the ADC continuous mode ISR is IRAM-Safe. When enabled, the ISR handler
- will be available when the cache is disabled.

- config ADC_CALI_EFUSE_TP_ENABLE
- bool "Use Two Point Values"
- default "y"
- help
- Some ESP32s have Two Point calibration values burned into eFuse BLOCK3.
- This option will allow the ADC calibration component to characterize the
- ADC-Voltage curve using Two Point values if they are available.
- config ADC_CALI_EFUSE_VREF_ENABLE
- bool "Use eFuse Vref"
- default "y"
- help
- Some ESP32s have Vref burned into eFuse BLOCK0. This option will allow
- the ADC calibration component to characterize the ADC-Voltage curve using
- eFuse Vref if it is available.
- config ADC_CALI_LUT_ENABLE
- bool "Use Lookup Tables"
- default "y"
- help
- This option will allow the ADC calibration component to use Lookup Tables
- to correct for non-linear behavior in 11db attenuation. Other attenuations
- do not exhibit non-linear behavior hence will not be affected by this option.

- config ADC_DISABLE_DAC_OUTPUT
- depends on SOC_DAC_SUPPORTED
- bool "Disable DAC when ADC2 is in use"
- default y
- help
- By default, this is set. The ADC oneshot driver will disable the output of the
- corresponding DAC channels:
- ESP32: IO25 and IO26
- ESP32S2: IO17 and IO18
- Disable this option so as to measure the output of DAC by internal ADC, for test usage.
