Subject: [PATCH 09/18] Delayed m68k setup of PCI IRQs to bus scan time
Date: Thu,  2 Oct 2014 05:07:37 +0100	[thread overview]
Message-ID: <1412222866-21068-10-git-send-email-matt@masarand.com> (raw)
In-Reply-To: <1412222866-21068-1-git-send-email-matt@masarand.com>

From: Matthew Minter <matt@masarand.com>

Currently PCI IRQs are assigned during mcf_pci_init which is only run
at boot time, this causes devices which are connected after boot time
to not receive an IRQ, this patch set fixes this by registering an IRQ
assignment function to be run later at device enable time.
