Use the newly added of_reserved_mem_region_to_resource() and of_reserved_mem_region_count() functions to handle "memory-region" properties. The error handling is a bit different in some cases. Often "memory-region" is optional, so failed lookup is not an error. But then an error in of_reserved_mem_lookup() is treated as an error. However, that distinction is not really important. Either the region is available and usable or it is not. So now, it is just of_reserved_mem_region_to_resource() which is checked for an error.

I guess a proper: EXPORT_SYMBOL(devm_ioremap_resource_wc) is missing. Neil
