Subject: [PATCH V4 03/29] PCI: Add IRQ mapping function pointers to pci_host_bridge struct
Date: Fri, 23 Oct 2015 06:03:36 +0100	[thread overview]
Message-ID: <1445576642-29624-4-git-send-email-matt@masarand.com> (raw)
In-Reply-To: <1445576642-29624-1-git-send-email-matt@masarand.com>

In order to defer IRQ assignment arches must be able to register functions
to map and swizzle interrupts. These registered functions are stored in
the pci_host_bridge struct.
