Right, that doesn't mean this is a great way of doing things, though - it's been a frequent source of errors in the past and is painful to debug as the data structures get rewritten during boot which is a bit of a surprise. > The alternative is creating a mulitude of platform devices for each possible > machine type using this driver. Yes, that's the normal way of handling this and is actually what the code was originally doing - there's a bunch of ifdefed devices in plat-samsung/devs.c. You usually have to do this anyway as the IPs move about so the resources need changing.
