Hi, I want to add support for the ADC device of the SAMA5D2 SoC. I may write a new driver because they are some changes about the register contents. Moreover, the new device doesn't fit the dt bindings (which are not very good since there is configuration stuff which is not relating to the SoC or to the board). My main concern is how to adress the configuration of my ADC, some examples: - choosing the resolution (some resolutions will impact the sampling time) - enabling the sleep mode or not - using offset correction - signed or unsigned conversions - etc. Having a look to other adc drivers, it seems resolution only depends on the SoC. Is there a generic solution? If not, can I create the files I need for my device in sysfs? Which adc driver would be the best to take as a reference? If you have some interesting discussions, I am interested too. I have browsed the iio mainling list up to september but I have not found answers.
