-From 125a18144253e3a3f4bcad24484ee9b590dc47c6 Mon Sep 17 00:00:00 2001

-Subject: [PATCH] PCI: of: Add inbound resource parsing to helpers
-
-Extend devm_of_pci_get_host_bridge_resources() and
-pci_parse_request_of_pci_ranges() helpers to also parse the inbound
-addresses from DT 'dma-ranges' and populate a resource list with the
-translated addresses. This will help ensure 'dma-ranges' is always
-parsed in a consistent way.
