Thinking again about what I've tried, I might have make the failure to add the interrupt-parent line to the mmc-section (where the gpio was specified) and not to the gpio(-controller) section where it might have belong too (again, there was no example and no documentation). But why I again bother you all with another mail, is that I don't like the fact that the irq-flags might have to be specified in the DT and the source (and they have to match). A solution might be to use the flags specified in the DT for the particular irq and ignore the flags specified as parameter to request_irq(). At least as long as DT isn't mandatory. And in the future, the flags could just be removed from the call to request_irq() depending (then visible too) only on the flags as specified in the DT.
