Hmm but in this case can't you just do it based on the compatible
flag? For legacy systems we also need to pass it in pdata.

Regarding omap_device, we should find a way to keep the dependencies
between drivers and the bus code down to minimum. So ideally things
like this would be only done using just the compatible flag. But the
pdata we cannot remove quite yet.
