Subject: [PATCH v5 06/29] PCI: Pass PCI domain number combined with root bus number
Date: Fri, 6 Mar 2015 17:33:23 +0800 [thread overview]
Message-ID: <1425634426-437-7-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1425634426-437-1-git-send-email-wangyijing@huawei.com>
Now we could pass PCI domain combined with bus number
in u32 argu. Because in arm/arm64, PCI domain number
is assigned by pci_bus_assign_domain_nr(). So we leave
pci_scan_root_bus() and pci_create_root_bus() in arm/arm64
unchanged. A new function pci_host_assign_domain_nr()
will be introduced for arm/arm64 to assign domain number
in later patch.
