179 	 * "pcie", accept the device as PCI (with a warning).
223  * of_pci_range_to_resource - Create a resource from an of_pci_range
226  * @res:	pointer to a valid resource that will be updated to
277  * of_range_to_resource - Create a resource from a ranges entry
279  * @index:	the 'ranges' index to convert to a resource
280  * @res:	pointer to a valid resource that will be updated to
453 	 * Normally, an absence of a "ranges" property means we are
454 	 * crossing a non-translatable boundary, and thus the addresses
458 	 * /ht nodes with no "ranges" property and a lot of perfectly
461 	 * a 1:1 translation at that level. It's up to the caller not to try
510  * Translate an address from the device-tree into a CPU physical address,
515  * that translation is impossible (that is we are not dealing with a value
516  * that can be mapped to a cpu physical address). This is not really specified
686  * Returns a pointer to the cell immediately following the translated DMA region.
908  * of_dma_get_range - Get DMA range info and put it into a map array
913  * and parse it.  Put the information into a DMA offset map array.
941 		/* Once we find 'dma-ranges', then a missing one is an error */
1116 	/* Get optional "reg-names" property to add a name to a resource */
1154  * Note that if your address is a PIO address, the conversion will fail if
1178  * of_iomap - Maps the memory mapped IO for a given device_node
1182  * Returns a pointer to the mapped memory
1199  * of_io_request_and_map - Requests a resource and maps the memory mapped IO
1200  *			   for a given device_node
1205  * Returns a pointer to the requested and mapped memory or an ERR_PTR() encoded
