Hi Andre,

thanks for you comments

Yes, I completely agree that using separate config for each SoCs is looks
overcomplicated because the only difference is the number of channels.
I thought about a DT property with channels number but I didn't find
another ADC driver with the same approach (except i2c ADC's with child nodes).

I'm sorry, I didn't quite understand what you're suggesting.

Oh, thanks for pointing that. I'll add it to the list in the next version.
