Add stm32mp23 and stm32mp25 compatibles. Three ADCs can be found on these SoCs, split into two blocks: - ADC12 are tightly coupled (common registers). - ADC3 is managed independently. Each ADC is a 12-bits successive approximation analog-to-digital converter, with up to 20 multiplexed channels that can be configured as single ended or differential. New property "st,adc-trigger-sel "
No need for space before "
allow to make the difference between the ADCs and to apply the correct trigger configuration.
I think "st,adc-trigger-sel" needs an example in the example bindings below.
STM32 ADC may be in a power domain: allow a single 'power-domains'.
