Placing these properties in a bus marks all child devices as requiring non-posted or posted MMIO mappings. If no such properties are found, the default is posted MMIO. of_mmio_is_nonposted() performs the tree walking to determine if a given device has requested non-posted MMIO. of_address_to_resource() uses this to set the IORESOURCE_MEM_NONPOSTED flag on resources that require non-posted MMIO. of_iomap() and of_io_request_and_map() then use this flag to pick the correct ioremap() variant.
