Don't they cause numerous resource conflicts while device nodes being instantiated as the platform devices?No; the driver knows that the HW is screwy and there's lots of register-range sharing going on, so it simply maps the registers, rather than reserving the physical address range and mapping it.Yes, it's clear that the driver should take special measures, I was asking about the platform device creation phase. What do you see in /proc/iomem?
The drivers don't request the memory region since doing so would cause conflicts. Hence, the regions don't show up in /proc/iomem.
Regions should show up after the platform device registration. They just show up as subregions of those when you request them. That's why I asked for your /proc/iomem.
