Armando	ded528e188	adc: no longer support adc2 oneshot mode on esp32c3 ... Due to HW limitation, we don't support this anymore. On c3, ADC2 under oneshot mode is not stable. However, you can enable CONFIG_ADC_ONESHOT_FORCE_USE_ADC2_ON_C3 to force use ADC2.

Armando	b4c90c44d2	adc: no longer support adc2 continuous mode on esp32c3 and esp32s3 ... Due to HW limitation, we don't support this anymore. On s3 and c3, ADC2 under continuous mode is not stable. However, you can enable CONFIG_ADC_CONTINUOUS_FORCE_USE_ADC2_ON_C3_S3 to force use ADC2.

Armando	236ba48efc	esp_adc: add a kconfig to disable dac on certain adc IOs ... Added a kconfig option. By default, when using ADC oneshot driver, it will disable DAC channels: - ESP32: IO25, IO26 - ESP32S2: IO17, IO18 if ADC2 is in use. You can disable this option, to measure DAC output, via internal ADC. This is for test usage.	2022-08-22 18:04:55 +08:00
