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.
