* stm32: Add CCRDY check to stm32g0 adcKevin O'Connor2022-07-251-0/+9
| | | | | | | The stm32g0 specification states that it is required to wait for the CCRDY flag to be raised after changing the channel configuration. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Fix ADC on stm32f042Kevin O'Connor2021-12-241-0/+1
| | | | | | It seems the stm32f042 chip needs a small delay during ADC enable. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Enable ADC support on stm32g0Kevin O'Connor2021-12-231-10/+49

* stm32: Rework register access on stm32f0_adc.cKevin O'Connor2021-12-231-34/+25
| | | | | | | | | | | Avoid read-modify-write operations where possible. The register values are in a known state so prefer absolute writes. Improve handling of race conditions with hardware updates. Remove the adc reference from "struct gpio_adc" as it is a constant. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
