2022-06-19iio: adc: stm32: fix vrefint wrong calibration value handlingOlivier Moysan
If the vrefint calibration is zero, the vrefint channel output value cannot be computed. Currently, in such case, the raw conversion value is returned, which is not relevant. Do not expose the vrefint channel when the output value cannot be computed, instead.

2022-06-19iio: adc: stm32: Fix IRQs on STM32F4 by removing custom spurious IRQs messageYannick Brosseau
The check for spurious IRQs introduced in 695e2f5c289bb assumed that the bits in the control and status registers are aligned. This is true for the H7 and MP1 version, but not the F4. The interrupt was then never handled on the F4. Instead of increasing the complexity of the comparison and check each bit specifically, we remove this check completely and rely on the generic handler for spurious IRQs.

2022-06-19iio: adc: stm32: Fix ADCs iteration in irq handlerYannick Brosseau
The irq handler was only checking the mask for the first ADCs in the case of the F4 and H7 generation, since it was iterating up to the num_irq value. This patch add the maximum number of ADC in the common register, which map to the number of entries of eoc_msk and ovr_msk in stm32_adc_common_regs. This allow the handler to check all ADCs in that module. Tested on a STM32F429NIH6.

2022-06-19iio: adc: stm32-adc: Use generic_handle_domain_irq()Sebastian Andrzej Siewior
The call chain generic_handle_irq(irq_find_mapping(domain, x)); could be replaced with generic_handle_domain_irq(domain, x); which looks up the struct irq_desc for the interrupt and handles it with handle_irq_desc(). This is a slight optimisation given that the driver invokes only one function and the struct irq_desc is used directly instead being looked up via irq_to_desc(). Use generic_handle_domain_irq().
