Antoine,

a side note on the interrupt-parent property above:

The parent simple-bus node already contains that property. If you
remove the property here, don't the interrupt routines go up the
hierarchy until they find an interrupt-parent set?

So, is it safe to get rid of the extra interrupt-parent property on
the adc node?
