Subject: [PATCH 07/18] Delayed cris setup of PCI IRQs to bus scan time
Date: Thu, 2 Oct 2014 05:07:35 +0100 [thread overview]
Message-ID: <1412222866-21068-8-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>
PCI IRQs are currently configured to be enabled once at boot in a
dedicated pass. This means that PCI devices which are hot-plugged after
boot time will not be given an IRQ, this patch-set fixes this by
registering the assignment function to be called later in the device
enable path.
