So, for one driver the extra arguments are: <reg> <start_bit> <stop_bit> For another driver (the stmmac example): <reg_offset> <reg_shift> Phew... Then we should really have a "syscon-raminit" property probably, so that at least plain "syscon" has a consistent syntax? > > > So, I'd rather drop additional arguments. > > > > Why would you like to have it encoded in DT? > > Where put the information then?

I thought we had this information in the driver already, but we haven't...
